منتجات تفاعل 1،5- ثنائي(4-توليل)-3- سيانو فورما زان مع النحاس الثنائي

The reaction of 1,5- di (4-Tolyl)-3-cyanoformazane with copper acetate in ethanol had been studied. The reaction gave two kinds of complexes. These complexes differ in their compositions, physical and chemical properties, although organic ligand is contained in both complexes in the anionic cyclic form. The first complex (I) has the structure [Cu ( OH) L], contains copper and organic ligand by proportion (1:1) .The second complex (II) has the structure [Cu L2 ], contains copper and organic ligand by proportion (1;2). The cyano group (-CN) contributes in coordination process in the complex (I). The bonds with copper are formatted by contribution anionic ligand, cyano group of other organic ligand and (-OH) group, which occur as result of hydration of copper acetate. In the complex (II) the cyano group does not contribute in coordination process with copper. The bonds with copper in complex (II) are formatted by contribution two organic ligands.
