In the title compound, [Zn(C8H5N2O2)2(H2O)], the ZnII ion is coordinated in each case by a carboxylate O atom and an imidazole N atom from two different benzimidazole-2-carboxylate (BIC) ligands and one water O atom in a trigonal-bipyramidal geometry. In the complex molecule, the two benzimidazole planes are twisted, making a dihedral angle of 55.93 (11)°. The three-dimensional framework is organized by intermolecular N—HO hydrogen bonding and O—HO interactions and π–π interactions between adjacent benzimidazole rings [centroid–centroid distance = 3.586 (3) Å].

In the title compound, C19H21NO3, the dihedral angle between the mean planes of the two benzene rings is 38.13 (12)°. The furan ring adopts an envelope-like conformation with the C atom bonded to the dimethyl groups displaced by 0.356 (2) Å from the plane through the other four atoms. In the crystal, molecules are linked into inversion dimers by weak C—HO intermolecular interactions.

In the title molecule, C12H12N6, the dihedral angles between the pyridine rings and the central dimethanimine–hydrazine group are 0.30 (3) and 13.94 (3)°. Two intramolecular N—HN hydrogen bonds stabilize the planar conformation of one pyridine ring with respect to its hydrazine-residue neighbour, whereas the other pyridine ring and an N-bonded H atom are rotated out of the plane and link the molecules into intermolecular N—HN chains propagating in [010].
