The title dinuclear manganese compound, [Mn2(C10H8N2)3(H2O)8](C7H6NO2)2(ClO4)2·2C10H8N2·4H2O, (I), has an inversion center located midway between the MnII ions. Each MnII ion has a distorted octahedral coordination environment, defined by two mutually cis N atoms from two different 4,4′‐bipyridine (4,4′‐bipy) ligands and four O atoms from four water molecules. The asymmetric unit contains cationic [Mn(4,4′‐bipy)1.5(H2O)4]2+, one isolated 4,4′‐bipy molecule, one 4‐aminobenzoate ion, one disordered perchlorate ion and two uncoordinated water molecules. In the dinuclear manganese cationic unit, one 4,4′‐bipy acts as a bidentate bridging ligand between two MnII ions, while the other two act only as monodentate terminal ligands, giving rise to a `Z‐type' [Mn2(4,4′‐bipy)3(H2O)8] host unit. These host units are linked to each other via face‐to‐face π–π stacking interactions between monodentate terminal 4,4′‐bipy ligands, generating a zigzag chain. The corners of these chains, defined by Mn(OH)4 units, are surrounded by the solvent water molecules and the carboxylate O atoms of the 4‐aminobenzoate ions, and all of these are connected to each other via strong O—H...O hydrogen‐bond interactions, leading to a three‐dimensional grid network with a large cavity running along the b axis of the unit cell. The isolated 4,4′‐bipy molecules, the 4‐aminobenzoate and perchlorate anions and the water molecules are encapsulated in the cavities by numerous hydrogen‐bond interactions.
