Аннотация

The new complexes [M(NKA)2(NCS)2(H2O)2], where M2+ = Co2+ (I), Ni2+ (II); NKA = C10H14N2O (N,N-diethylpyridine-3-carboxamide, nicotinic acid diethylamide, nikethamide), have been synthesized and studied by chemical and X-ray diffraction analyses and IR spectroscopy. The single-crystal X-ray diffraction analysis of these complexes has shown that they crystallize in triclinic system with space group (Formula presented.). Despite similar molecular structures of the two complexes, the orientation of molecules in a crystal cell is different in them. The coordination polyhedron of the metal atom is a distorted octahedron built of the O atoms of two coordinated water molecules, the two N atoms of the pyridine rings of two NKA molecules, and the two N atoms of rhodanide groups. The packing of molecules leads to the appearance of additional stacking interactions with the formation of a branched network of hydrogen bonds between coordinated water molecules and NKA carbonyl groups in the structures of these complexes.
