In the crystal structure of the title compound, [Ni(NCS)2(C7H7NO)2(CH3OH)2], the Ni2+ cations are coordinated by two thiocyanate anions, two 3-acetylpyridine ligands and two methanol molecules within slightly distorted NiN4O2 octahedra. The asymmetric unit consists of one Ni2+ cation, which is located on a center of inversion, as well as one thiocyanate anion, one 3-acetylpyridine ligand and one methanol molecule in general positions. The discrete complexes are linked by two pairs of O—H
O hydrogen bonds between the hydroxy H atom and the acetyl O atom into chains along the b axis.

In the crystal structure of the title compound, [Co(NCSe)2(C7H7NO)2(H2O)2], the Co2+ cation is coordinated by two selenocyanate anions, two 3-acetylpyridine ligands and two water molecules within a slightly distorted CoN4O2 octahedron. The asymmetric unit consists of one Co2+ cation, which is located on a center of inversion, as well as one selenocyanate anion, one 3-acetylpyridine ligand and one water molecule in general positions. Whereas one of the water H atoms makes a classical O—HO hydrogen bond, the other shows a O—HSe interaction.

In the crystal structure of the title compound, [Cd(NCSe)2(C7H7NO)2]n, the Cd2+ cation is coordinated by two 3-acetylpyridine ligands and four μ-1,3-bridging selenocyanate anions within a slightly distorted CdN4Se2 octahedron. The asymmetric units consists of one Cd2+ cation, which is situated on a center of inversion, as well as one selenocyanate anion and one 3-acetylpyridine ligand in general positions. The metal cations are μ-1,3-bridged via the selenocyanate anions into chains along the a axis.
