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.

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.

In the title complex, [Co(C5H4N2O3)6](ClO4)2, six 4-nitropyridine N-oxide (npo) ligands coordinate to the CoII atom via their N-oxide O atoms, resulting in an octahedral CoO6 grouping. The CoII ion occupies an inversion centre. A short contact of 2.841 (12) Å is observed between a pyridine N atom and a perchlorate O atom.

In the mononuclear title complex, [Co(C12H11N2O2)2(C2H6O)2], the six-coordinate CoII atom lies on an inversion centre and is coordinated by six O atoms, two from the ethanol molecules and the remaining four from two chelating 4-acetyl-3-methyl-1-phenyl-5-pyrazolonate monovalent anions. O—HN hydrogen bonds involving the ethanol O—H and the pyrazolonate N atoms stabilize the structure.
