摘要: Abstract The crystal structure of [Ni(H2O)4(NA)2](NO3)2.2H2O (NA[dbnd]nicotinamide) has been determined. complex cation a monomeric pseudo-octahedral configuration about Ni(II). basal plane contains four oxygen atoms coordinated water molecules and axial positions are occupied by heterocyclic nitrogen the two nicotinamide ligands. other not coordinated. Spectroscopic, magnetic thermal data in agreement with structural results. Trends Ni[sbnd]N Ni[sbnd]O interatomic distances similar complexes discussed.
