Complexes of Transition Metal(II) Thiocyanates with 1, 2, 4-Triazole

Abstract

The preparation of complexes containing 1, 2, 4-triazole (trz) is described. The general formula is M(trz)2(CNS)2 with M = Mn, Fe, Co, Ni, Cu and Zn. For M = Ni two isomeric Compounds have been isolated. The infrared spectra of the Ni Compounds are assigned on the basis of the assignment for the free 1, 2, 4-triazole. One of the Ni Compounds is a tri-nuclear complex according to its infrared spectrum. The other complexes are isomorphous, with exception perhaps of the Cu complex. For these Compounds a polynuclear structure is proposed. © 1977, Walter de Gruyter. All rights reserved.
