Synthesis and Spectroscopic (IR) Studies of Complex Compounds of Some 3D Metals with N,N-dimethylformamide

Complex compounds of sulphates and chlorides of cobalt (II), nickel (II), copper (II), manganese (II), cadmium (II) and zinc with N, N-dimethylformamide, as well as mixed acidoligand complex compounds of cobalt (II), nickel (II), manganese (II) and copper (II) with N,N-dimethylformamide were synthesized. In order to study the rules of coordination of N,Ndimethylformamide and thiocyanate groups, IR spectra of synthesized complex compounds were studied. Based on the study of IR spectra, it was found that in all synthesized complex compounds, the coordination of the N,Ndimethylformamide molecule with complexing metals is carried out by the oxygen atom of the carbonyl group. For sulfate and chloride compounds of cobalt (II), nickel (II) and manganese (II) with N, N-dimethylformamide, an octahedral structure of synthesized complexes is proposed, and in the case of copper (II) and cadmium, a tetrahedral structure.
