Cadmium cyanide complexes with heterocyclic thiones: Solid state and solution NMR studies

摘要

Cadmium(II)cyanide complexes of various thiones (imidazolidine-2-thione, diazinane-2-thione and their derivatives) have been prepared and characterized by elemental analysis, IR and solid as well as solution NMR spectroscopy. It appears from the IR data that all complexes are non-ionic [(>C=S)(2)Cd(CN)(2)]. An upfield shift in the C-13 NMR and downfield shifts in the H-1 NMR are consistent with the sulfur coordination to cadmium(H). The solid Cd-113 NMR data show the presence of different coordination numbers in some complexes. (C) 2008 Elsevier B.V. All rights reserved.
