Abstract
In recent years nucleophilic addition between the cyanate group and pyrazole or its methylderivative in the Cu(1I) coordination sphere has been thoroughly From the systems Cu(I1)-NCO–pyrazole-type ligand as well as the compounds in which a nucleophilic reaction was realized, isomeric cyanato complexes were also separated (“coligand” icomerisrn). Earlier investigations showed that the non-linear pseudohalide anions dicyanamide, N(CN), and tricyanmethanide, C(CN), closely resemble the cyanate ligand.5 Based on the pseudochalcogen character of NCN and C(CN), groups: these pseudohalides may be classified as pseudochalcogenates. We supposed therefore that in systems with these non-linear pseudohalides nucleophilic addition also could take place and the occurence of further coligand isomers could be expected.Keywords
