Synthesis inorganic complexes of new pseudohalogen of type Acetyldicyanomethanide

Aseries of mixed acetyldicyanomethanide amine complexes of some bivalent 3d-metals.Infrared spectroscopic IR and UV investigations are indicating that the ambident acetyldicyanomethanide ligand shows an unusual variability of the preferred donor atom . O-or N-coordination of the monodentate anionic ligand in the tetra –pyridine complexes as well as a bridging function of the acetyldicyanomethanide ligand in the polymeric octahedral or distorted octahedral di-pyridine complexes preferrably with .
