In the title complex, [Mn2(C15H13N2O3)3]ClO4·CH3OH, the two MnII ions are bridged by two phenolate O atoms from two ligands, forming an Mn2O2 quadrangle. Each MnII ion has a distorted octahedral coordination geometry. One MnII ion is coordinated by two N atoms and four O atoms from two ligands, and the other is coordinated by one N atom and five O atoms from three ligands. A dimer is formed by intermolecular N—HO hydrogen bonds. The dimers, perchlorate anions and methanol solvent molecules are further connected into a chain along [01] through N—HO and O—HO hydrogen bonds.

In the title compound, C16H16N2O4·H2O, the dihedral angle between the two benzene rings is 12.4 (2)° and the molecule adopts an E configuration with respect to the C=N bond. There are intramolecular O—HN and O—HO hydrogen bonds in the hydrazone molecule, which both generate S(6) rings. In the crystal structure, molecules are linked by N—HO and O—HO hydrogen bonds, forming layers parallel to the ab plane. The crystal studied was a non-merohedral twin with a domain ratio of 0.887 (3):0.113 (3).
