Stoichiometry and stereochemistry of the solid thiocyanate nickel(II) complexes with various piperidine ligands have been studied. The prepared complexes can be arranged into three groups by their composition: the first group includes the compound Ni(NCS) 2(pip) 4 (pip=piperidine) with monomeric pseudooctahedral configuration; the second one contains pentacoordinated complexes Ni(NCS) 2L 3 (L=4-Mepip; 3,5-Me 2pip); the third group includes the complexes Ni(NCS) 2L 2 with the polymeric pseudooctahedral configuration (L=pip, 4-Mepip and 3,5-Me 2pip) or with the square-planar configuration (L=2-Mepip and 2,6-Me 2pip). These results are discussed in relation to the corresponding complexes with pyridine ligands.
