Crystal And Molecular Structures

The crystal and molecular structures of tetraethyl- (1), tetra-η-propyl- (2) and tetra-nbutylammonium tetrachloroantimonate(III) (3) were determined by X-ray analysis. There are discrete Sb4Cl164- (1) and Sb2Cl82- (2 and 3) anions. The Sb-Cl bond lengths vary in the range between 234 and 326 pm, and are explained as in a three centre-four electron situation. The vibrational spectra of the anions are briefly discussed

Heterocyclic Cations

The crystal and molecular structures and magnetic properties of two new complexes (HMepy)2[CuCl4]·2H2O, 2, and (H2Me2ppz)[CuCl4], 3, formed by tetrachlorocuprate(ii) anions and organic heterocyclic cations, have been determined by the analysis of their X-ray diffraction data, magnetic susceptibility behaviour and EPR spectral parameters.
