SHORT NOTE

The synthesis, spectral and magnetic properties of complexes of some transition metal chlorosulphates with thiazoles and thiocarhamate

(Received 11 September 1993; in final form 13 October 1993; accepted 9 November 1993)

COORDINATION compounds of transition metal chlorosulphates of the type M(L),(SO&I),, M = Co(II), Ni(II), Zn(II), Mn(I1) and Cu(II), L = 2-acetamido-S-nitrothiaxole, 2-aminothiaxole, 2-mercaptobenzothiazole and sodium diethyl dithiocarbamate with n= 1, 2 and 4 are reported. The chlorosulphate anion is coordinated to the metal in a unidentate as well as a bidentate manner in different complexes, which show a strong interaction of the SO$l- anion and the complex cations (ML,)+.

All the complexes of Co(I1) and Mn(I1) are supposed to have octahedral geometry. The Ni(I1) complexes are probably tetragonally octahedral, whereas the Zn(I1) complexes are tetrahedral. However, a square planar configuration is tentatively suggested for Cu(I1) complexes.
