Abstract

Cu(NO3)(2). 3H(2)O reacts with 1 equiv. of the tetradentate Schiff base N,N'-bis[1-(2-pyridyl)ethylidene]ethane-1,2-diamine (LA) in refluxing acetone to yield the [CuLA(ONO2)(H2O)](NO3) complex in ca. 80% yield. The structure of this salt has been determined by single-crystal X-ray crystallography. The copper is six-coordinated with the L-A ligand in the equatorial plane and weakly bonded aqua and nitrate ligands above and below this plane. The complex cation is hydrogen-bonded to the nitrate counter-ion. The complex was also characterized by elemental analyses, molar conductivity, room-temperature magnetic susceptibility and spectroscopic (i.r., far-i.r., u.v.-vis, e.s.r.) studies. The data are discussed in terms of the nature of bonding and the known structure. Transition Metal Chemistry

2. Rare M(7)O(2) double tetrahedral core in molecular species: preparation, structure and properties of [Zn(7)O(2)(O(2)CMe)(10)(1-Mein)(2)] (1-Meim = 1-methylimidazole)

Abstract

The 2:1 reaction between Zn(O(2)CMe)(2). 2H(2)O and 1-Meim in refluxing MeCN gives [Zn(7)O(2)(O(2)CMe)(10)(1-Meim)(2)] 1 which comprises two vertex-sharing tetranuclear Zn(4)(mu(4)-O)(eta(1): eta(1) :mu(2)-O(2)CMe)(5)(1-Meim) units; solid-state (13)C and (15)N NMR spectra reveal structural details of the complex.

3. Preparative and Vibrational Spectroscopic Studies of Anilinium Salts Containing the [Hg2cl6]2-, [Hg2cl4x2]2-, [Cdhgi6]2-, [Cdhgi4br2]2- and [Cdhgbr4i2]2- Ions (X = Br, I)

Abstract

Synthetic procedures are described that allow access to anilinium salts containing the complex anions [Hg2Cl6]2-, [Hg2Cl4X2]2- (X = Br, I), [CdHgI6]2-, [CdHgI4Br2]2- and [CdHgBr4I2]2-. Isolated dimeric structures are proposed for the new complexes in the solid state, using X-ray powder patterns, Far-IR and Raman spectra. The spectral detail is greatly enhanced in measurements at low temperature (approximately 100 K). Zeitschrift Fur Naturforschung Section B-a Journal of Chemical Sciences
