Abstract: Solid cyanatonickel(II) complexes of the composition Ni(NCO)₂L₄, where L = imidazole, 2-methyl-, 2-ethyl-, 2-phenylimidazole, and Ni(NCO)₂(1,2-dimethylimidazole)₂.2H₂O were prepared. Structural characteristics of these complexes were determined by infrared and electronic spectroscopy and magnetic moment measurements. As ascertained, the Ni(II) atom in complexes under study has a pseudooctahedral structural arrangement and the NCO groups are terminally bonded through nitrogen. The axial bonds in Ni(NCO)₂(1,2-dimethylimidazole)₂.2H₂O are formed through the bidentate nitrogen atom of the cyanato groups, and molecules of water are linked through hydrogen bridges.
