The title lanthanide complexes, [Ln(DAPBH2)(CH3OH)(H2O)3]Cl3·2CH3OH [Ln III = Tb and Dy; DAPBH2 = 2,6-diacetylpyridine bis(benzoylhydrazone), C23H21N5O2], are isotypic. The central lanthanide ions are nine-coordinate, being ligated by three N and two O atoms from the pentadentate DAPBH2 ligand, and four O atoms from the coordinated methanol molecule and three coordinated water molecules. The coordination geometry of the lanthanide ion is a distorted capped square antiprism. In the crystals, the various components are linked by O—H...Cl, N—H...Cl and O—H...O hydrogen bonds, forming three-dimensional supramolecular frameworks. Within the frameworks, there are C—H...Cl and C—H...O hydrogen bonds and offset π–π interactions (intercentroid distance ca 3.81 Å).
