Three pseudopolymorphs of a phenoxo-bridged binuclear manganese(III) complex, [Mn(L)(N3)]2 where L = [N,N'-bis(2-hydroxyacetophenylidene)]propane-1,2-diamine could be synthesized using same reactants but different solvents. The syntheses of the unsolvated isomer [Mn(L)(N3)]2 (1) and a hydrated isomer [Mn(L)(N3)]2·3.66H2O (2) have been achieved in acetone and methanol medium, respectively, while another previously reported complex [Mn(L)(N3)]2·2C2H5OH (3) was obtained from a mixed solvent containing ethanol. The pseudopolymorphs 1, 2 and 3 crystallize in the space groups P21/c, P21/n and P21/n, respectively. Their 3D supramolecular structures have been compared to notice that the molecular building blocks are held by weak intermolecular C-H?p, C–H?O or van der Waals interactions. While the compound 1 is an unsolvated pseudopolymorph, 2 and 3 contain water and ethanol, respectively as guest molecules in their lattices.
