A family of inorganic-organic hybrid vanadium selenites with zero, one-, two-, and three-dimensional structures, (1,10-phen)2V2SeO7, (2,2'-bipy)VSeO4, (4,4'-bipy)V2-Se2O8, and (4,4'-bipy)2V4Se3O15.H2O were synthesized and analyzed hydrothermally by single-crystal X-ray diffraction.

Herein, we present a facile colloidal method to synthesize the high-quality AgGaS 2 nanocrystals (NCs) within 2 min via exploiting the high-reactivity S precursor and then extend this synthetic strategy to the preparation of AgGaS 2 /ZnS core-shell NCs by a one-pot method without prior purification of AgGaS 2 core. The as-synthesized samples were structurally characterized to confrim the formation of AgGaS 2 /ZnS core-shell NCs. The energy band gap of the AgGaS 2 /ZnS NCs can be effectively tunable from 2.98 to 2.83 eV by the control of their nonstoichiometry and further continuously decreases to 1.90 eV by the preparation of alloyed AgGa x In 1- x S 2 /ZnS NCs (1 ≤ x ≤ 0). Benefitting from the efficient band gap modulations, the photoluminescence (PL) colors of the AgGaS 2 -based NCs can cover almost the whole visible region from blue (460 nm) to red (671 nm). Our work demonstrates the one-pot synthesis of AgGaS 2 /ZnS core-shell NCs and their band gap engineering, which is of crucial in scalability toward industrial application and in tailoring optical characteristics of I-III-VI 2 materials.

A new one-dimensional hybrid copper iodate, (2,2'-bipy)(2)Cu(2)(IO(3))(3)(+), with potentially large void volume and a high amount of accessible volume, was synthesized by hydrothermal reactions and characterized by single crystal X-ray diffraction.

This paper reports the synthesis and crystal structure of a novel mixed valence ruthenium(II,III) compound, (NH(4))(3)Ru(2)(hedp)(2).2H(2)O (1), where hedp represents 1-hydroxyethylidenediphosphonate. It has a two-dimensional structure in which the paddlewheel diruthenium(II,III) units of Ru(2)(hedp)(2) are cross-linked through the phosphonate groups. The layers are stacked along the [100] direction with strong intra- and interlayer hydrogen bonds. Primary magnetic results are presented.

A novel organically templated cobalt-vanadium oxalate, (C(2)H(10)N(2))[Co(2)(C(2)O(4))V(4)O(12)], was synthesized under mild hydrothermal conditions and characterized by single-crystal/powder X-ray diffraction, infrared spectroscopy, and thermogravimetric analysis. The compound crystallizes in an orthorhombic system with space group Cmcm and cell parameters a = 11.527(2) A, b = 9.9476(18) A, c = 14.780(3) A. The compound possesses 3-dimensional topologies with sodalite analogue structure and is constructed by C(2)O(4)-incorporated beta cage units. On the basis of the results of TG/DTA analyses, the structure is thermally stable up to approximately 573 K.
