In the title complex, [Zn(N3)2(C7H10N2)2], the ZnII atom is coordinated by two N atoms from two 4-(dimethylamino)pyridine (DMAP) ligands and by two N atoms from two azide anions in a distorted tetrahedral coordination geometry. In the crystal, weak C—H
N hydrogen bonds between the DMAP and azide ligands link these discrete complex molecules into a three-dimensional supramolecular network.

The title layered polymer, [Co(N3)2(C7H10N2)2]n, contains CoII, azide and 4-(dimethylamino)pyridine (4-DMAP) species with site symmetries m2m, 2 and m, respectively. The Co2+ ion adopts an octahedral coordination geometry in which four N atoms from azide ligands lie in the equatorial plane and two 4-DMAP N atoms occupy the axial positions. The CoII atoms are connected by two bridging azide ligands, resulting in a chain parallel to the c axis.

In the anion of the title compound, (C7H11N2)[CoCl3(C7H10N2)], the CoII ion is coordinated by one N atom from a 4-(dimethylamino)pyridine (DMAP) ligand and three Cl atoms, forming a CoNCl3 polyhedron with a distorted tetrahedral geometry. In the crystal, cations and anions are linked via weak N—HCl and C—HCl hydrogen bonds. Double layers of complex anions stack along the b- axis direction, which alternate with double layers of 4-(dimethylamino)-pyridinium cations.

In the title salt, [Co(C7H9NO)2(H2O)2]Cl2, the CoII cation, located on an inversion center, is N,O-chelated by two hydroxyethylpyridine ligands and coordinated by two water molecules in a distorted O4N2 octahedral geometry. In the crystal, the Cl− anions link with the complex cations via O—HCl hydrogen bonds, forming a three-dimensional supramolecular architecture. π–π stacking is observed between the pyridine rings of adjacent molecules [centroid–centroid distance = 3.5810 (11) Å].
