Abstract: Complexes of the type Ni(NCS)₂B_n (B is methylamine and ethylamine; n = 2 and 4) and two isomers of complex Ni(NCS)₂(diethylamine)₂ were prepared. From the spectral and magnetic data it follows that the red isomer has a square-planar configuration with end-bonded NCS groups, while the green isomer is pseudooctahedral polymer complex with both terminal and bridge-bonded (trifunctional) NCS groups. Complexes Ni(NCS)₂B_n have a pseudooctahedral configuration with end-bonded (n =4) or bridge-bonded (n = 2) NCS groups. It was found that the formation of the above-mentioned isomers is connected (besides the appropriate bonding properties of ligands) also with the steric effect of diethylamine in a similar way as in complexes with 2-substituted derivatives of pyridine.
