Abstract:
The temperature dependence of the magnetic susceptibility and the electron paramagnetic resonance spectra of the thiazole complexes dichloro- and dibromobisthiazolecopperII are reported, along with a complete three-dimensional X-ray structure analysis of the dichloro complex based on counter data. The dichloro complex, CuC3H3NS2C12, crystallizes in space group of the monoclinic system with two independent formula units in a cell of dimensions a 7.3326, b 3.8534, c 17.49317 angstrom, and Beta 93.701. The structure has been refined by full-matrix least-squares methods using 1172 independent data to a final value of the conventional R-factor on F of 0.028. The structure, which consists of infinite chains of doubly chloride bridged copperII ions, is reminiscent of those of the pyridine analogs, with a Cu-Cu separation of 3.8534 angstrom and bridging angle of 91.892. The magnetic data and interchain exchange interactions are discussed in the light of the structural properties of the systems.
