metal-organic compounds
The title molecular complex, [Zn(H2O)6](ClO4)2·2C6H8N2O2, consists of neutral 2,5-dimethylpyrazine 1,4-dioxide molecules, a hexaaquazinc(II) cation and perchlorate anions, linked through Coulombic attraction and hydrogen bonding. Half the neutral molecules lie in general positions, and the other half are on inversion centers.

The title compound, [Ni(NCS)2(C6H7NO)2(H2O)2]·H2O, consists of a mononuclear complex and an uncoordinated water molecule. The nickel(II) ion has a distorted octahedral coordination, formed by two N atoms from two thiocyanate anions and four O atoms from two water molecules and two 4-methylpyridine N-oxide molecules. The uncoordinated water molecules and the complex are connected by O—HO and O—HS hydrogen bonds.

In the title mononuclear complex, [Co(NCS)2(C5H5NO)2(H2O)2], cobalt(II) has a distorted octahedral coordination formed by two N atoms from two thiocyanate anions and four O atoms from two water molecules and two pyridine N-oxide molecules. The complexes are connected to each other by O—HO and O—HS hydrogen bonds.
metal-organic compounds
The title structure, (C5H7N2)2[Co(NCS)4], comprises discrete monovalent 4-aminopyridinium cations and divalent tetrathiocyanatocobaltate(II) anions. The cations and anions are linked via N—HS hydrogen bonds [NS = 3.264 (4)–3.640 (6) Å] to form a three-dimensional framework.
