Summary
Complexes having the empirical formula M(BCTA)2X2, (M=Zn or Hg; X=Cl, Br or I) and Cd(BCTA)X2 (X=Cl, Br or I) are formed by reaction of benzenocarbothioamide (BCTA) with anhydrous zinc(II), cadmium(II) or mercury(II) halides and have been isolated and characterized by elemental analysis, conductance and molecular weight measurements, and by i.r., Raman and1H n.m.r. spectral studies. They are not appreciably ionized in acetonitrile solvent. The i.r.v(CN) shift to higher a frequency andv(CS) shift to a lower frequency indicate that BCTA is bound to the metals through sulphur. A tetrahedral structure withC 2v symmetry is proposed for [M(BCTA)2X2] on the basis of the i.r. and Raman data, and a dimeric tetrahedral structure withC 2h skeletal symmetry for Cd(BCTA)X2. The1H n.m.r. spectral measurements also show coordination through the sulphur atom.
