The carbonyl cluster compound [GeRu6(CO)18HI] is unique in regard to its structure and bonding with a GeRu6 cluster core, a planar GeRu4HI unit, extensive multi‐center bonding, and an aromatic ring current similar to benzene (9‐10 nA T−1). The open‐shell cluster core is a Ge‐centered five‐membered Ru4(Ru2) ring with CO ligands and an additional H and I atom, each bridging two Ru atoms on opposite sides of the cluster core. The compound is prepared at 130 °C in a weakly‐coordinating ionic liquid. [ABSTRACT FROM AUTHOR]

The pseudo-ternary tin(II) halide [BMPyr]2[SnCl4] can be obtained just by mixing the starting materials [BMPyr]Cl and SnCl2 at room temperature without additional solvents. The compound shows bright Sn(II)-based emission of deep-red light (λmax: 740 nm) with a quantum yield of 88 ± 3% after optimised synthesis. Characterization is performed by X-ray structure analysis, infrared and fluorescence spectroscopy. Exemplary fluorescent thinfilms are realized by solvent processing. [ABSTRACT FROM AUTHOR]

During outstanding research in the late 1950s in Munich, which led to the development of the Wacker process for converting ethene into acetaldehyde by catalysis of PdCl2, black insoluble nitrosyl‐palladium chloride (PdCl(NO)) was obtained. More than sixty years after its first synthesis, its crystal structure was now determined by X‐ray diffraction. PdCl(NO) (mP16, P21/c, a=10.2684(5), b=4.0737(2), c=7.8456(4) Å, β=111.125(1)°, wR2=0.0572) consists of distorted Pd4Cl4 octagons in chair arrangement to which four distorted Pd2Cl2 squares are annulated on every second edge. In this arrangement each of the two Pd atoms of the squares are connected to one N−O group, bonded alternatively up and down to the Pd atoms with a Pd−N−O angle of 129°. Such a square has the composition of the dimer which was found in the mass spectrum at 343.6 m/e. The octagons with four squares are interconnected to corrugated layers in the b‐c‐plane as a two‐dimensional polymer. [ABSTRACT FROM AUTHOR]

Introduction: The WHO estimates that each year 5 million people are left permanently disabled after stroke. Adjuvant treatments to promote the effects of rehabilitation are urgently needed. Cortical excitability and neuroplasticity can be enhanced by non-invasive brain stimulation but evidence from sufficiently powered, randomized controlled multi-center clinical trials is absent. Methods: Neuroregeneration enhanced by transcranial direct current stimulation (tDCS) in stroke (NETS) tested efficacy and safety of anodal tDCS to the primary motor cortex of the lesioned hemisphere in the subacute phase (day 5–45) after cerebral ischemia. Stimulation was combined with standardized rehabilitative training and repeatedly applied in 10 sessions over a period of 2 weeks in a planned sample of 120 patients. Primary outcome parameter was upper-extremity function at the end of the 2-weeks intervention period of active treatment or placebo (1:1 randomization), measured by the upper-extremity Fugl-Meyer assessment. Sustainability of the treatment effect was evaluated by additional follow-up visits after 30 and 90 days. Further secondary endpoints included metrics of arm and hand function, stroke impact scale, and the depression module of the patient health questionnaire. Perspective: NETS was aimed at providing evidence for an effective and safe adjuvant treatment for patients after stroke. Trial registration: ClinicalTrials.gov Identifier NCT00909714.

The halogenido stannates(II) [BMIm][Sn3Cl7] and [BMIm][Sn4Br9] are obtained by ionic‐liquid‐based synthesis with SnX2 and [BMIm]X (X=Cl, Br; [BMIm]=1‐butyl‐3‐methylimidazolium) near room temperature (45–50 °C). Both form colorless, moisture‐sensitive crystals and exhibit layered anionic networks. [BMIm][Sn3Cl7] contains "horseshoe"‐like ∞1(SnCl1/1Cl2/2) chains that are linked via [SnCl3]− anions to ∞2[Sn3Cl7]− zigzag‐planes. [BMIm][Sn4Br9] contains a complex ∞2[Sn4Br9]− network with altogether four different crystallographic Sn2+ sites and different coordination. For comparison with these complex halogenido stannates(II), PbCl2/PbBr2 are reacted with similar conditions, which, however, only results in [BMIm][PbCl3] containing ∞1[PbCl3]− chains. Beside the crystal structures, the thermal and optical properties are examined and feature certain emission of visible light for all title compounds at room temperature. Whereas the quantum yields of [BMIm][Sn4Br9] (3 %) and [BMIm][PbCl3] (21 %) are low, [BMIm][Sn3Cl7] shows surprisingly efficient photoluminescence with a quantum yield of 46 %.

The novel tin(II) oxychloride [BMIm][Sn 5 O 2 Cl 7 ] (BMIm = 1-butyl-3-methylimidazolium) is obtained by the room-temperature reaction (25 °C) of black SnO and SnCl 2 in [BMIm]Cl/SnCl 2 as an ionic liquid. The title compound can be described as composed of noncharged, infinite ∞ 1 (Sn 2 OCl 2 ) strands that are embedded in a saline matrix of [BMIm] + and [SnCl 3 ] - . The ∞ 1 (Sn 2 OCl 2 ) strands consist of a backbone of edge-sharing OSn 4/2 tetrahedra, which represent one-dimensional (1D) strands cut out of the layer-type structure of SnO. In [BMIm][Sn 5 O 2 Cl 7 ], the ∞ 1 (Sn 2 OCl 2 ) strands, which mimic a 1D semiconductor, are terminated by chlorine atoms, whereas they are interconnected by oxygen atoms in the 2D semiconductor SnO. The view of the noncharged ∞ 1 (Sn 2 OCl 2 ) strands in a saline [BMIm][SnCl 3 ] matrix is validated by dissolution experiments. Thus, electron microscopy and Raman spectroscopy show a deconstruction of [BMIm][Sn 5 O 2 Cl 7 ] single crystals after treatment with chloroform with a dissolution of [BMIm][SnCl 3 ], the formation of SnCl 2 needles, and tin oxide as a solid remain.

GaSeCl 5 O is a new inorganic molecular compound prepared from SeO 2 , SeCl 4 , and GaCl 3 at 50 °C in quantitative yield. The structure of the title compound is described by GaCl 3 (OSeCl 2 ) molecules with a tetrahedrally coordinated Ga atom and a pseudo-tetrahedrally coordinated Se atom (including lone pair of Se(IV)) that are bridged by oxygen. GaSeCl 5 O crystallizes in the polar chiral space group P 6 1 , which is rarely observed for molecular structures. The compound is characterized by X-ray structure analysis based on single crystals and powder samples, thermogravimetry, infrared and Raman spectroscopy as well as by second harmonic generation (SHG) measurements. The experimental data are complemented by density functional theory calculations. GaSeCl 5 O shows one of the strongest SHG signals known in the visible part of the electromagnetic spectrum (480-700 nm) with an SHG intensity 10 times higher than potassium dihydrogen phosphate (KDP). This is in accordance with the phase matchability and a strong dipole moment (| μ | = 8.3 D for a molecule in the crystal lattice). Such a strong SHG effect is also remarkable since GaSeCl 5 O-unlike most of the materials with strong SHG intensity-is an inorganic molecular compound.
