Magnetic and Structural Characterization of Dibromo- and Dichlorobis(thiazole)copper(II).
Abstract
The temperature dependence of the magnetic susceptibility and the electron paramagnetic resonance spectra of the thiazole complexes dichloro- and dibromobis(thiazole)copper(II) are reported, along with a complete three-dimensional X-ray structure analysis of the dichloro complex based on counter data. The dichloro complex, Cu(C3H3NS)2C12, crystallizes in space group of the monoclinic system with two independent formula units in a cell of dimensions a = 7.332(6), b = 3.853(4), c = 17.493(17) angstrom, and Beta = 93.70(1). 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 copper(II) ions, is reminiscent of those of the pyridine analogs, with a Cu-Cu separation of 3.853(4) angstrom and bridging angle of 91.89(2). The magnetic data and interchain exchange interactions are discussed in the light of the structural properties of the systems.
