Synthesis, spectroscopic and structural investigation of Zn(NCS)2(nicotinamide)2 and [Hg(SCN)2(nicotinamide)]n

The zinc(II) and mercury(II) thiocyanate complexes with nicotinamide, bis(nicotinamide-N)-bis(thiocyanato-N)zinc(II) (1) and catena[nicotinamide-N-(mu-thiocyanato-S, N)(thiocyanato-S)mercury(II)] (2) have been prepared and characterized by spectroscopic, thermal and X-ray crystallographic methods. The vibrational bands of diagnostic value are compared to the values of the free ligand and the data are in good correlation with X-ray results. The centrosymmetrical hydrogen bonded dimers are found, R22(10) in 1 and R22(8) in 2.
