In the presence of a non-coordinating solvent, CH2Cl2, thioacetamide coordinated to Cp2ZrCl2 through C=S unit with participation of the NH group. This complexation was proved by the new bands appearing in Zr-N and Zr-S stretching region, also by the blue shift of thioamide band I and the red shift of thioamide band IV of thioacetamide. Deprotonated ethanethiol with Cp2ZrCl2 gave a dimeric complex with the formula (Cp2ZrClSCH2CH3)2. Without deprotonation ethanethiol did not coordinate to Cp2ZrCl2.30 cm.Heterocyclic compounds.xv, 76 leaves;
