In the title compound, [Co(C18H18N2O4)Cl(H2O)]·C3H7NO, the CoIII ion is six-coordinated by a tetradentate 6,6′-dimethoxy-2,2′-[ethane-1,2-diylbis(nitrilomethanylylidene)]diphenolate ligand, with a chloride ion and an aqua ligand in the apical positions. The compound crystallized as a dimethylformamide (DMF) monosolvate. In the crystal, complex molecules are linked via O—Hwater
O hydrogen bonds to form a dimer-like arrangement. These dimers are linked via a C—HCl interaction, and the DMF molecule is linked to the complex molecule by C—HO interactions.

In the structure of the title complex, [ZnCl2(C6H8N4)2], the ZnII atom has a distorted octahedral geometry. Two cis Cl− ions and four N atoms belonging to two different 2-(1-hydrazinylideneethyl)pyrazine ligands coordinate the ZnII atom, forming two five-membered Zn—N—C—C—N rings. The dihedral angle between the planes of these metallocycles is 88.13 (4)°. The organic ligands are essentially planar (r.m.s. deviations from planarity = 0.072 and 0.040 Å). Intermolecular N—HN and N—HCl interactions join the molecules into a three-dimensional framework.
