In the title complex, [Mn(C(13)H(14)N(2))(4)(H(2)O)(2)](ClO(4))(2)·1.5H(2)O, the Mn(II) ion is coordinated by four N atoms from four different 1,3-di-4-pyridyl-propane mol-ecules and two O atoms from two coordinated water mol-ecules, leading to a distorted MnN(4)O(2) octa-hedral geometry. Each 1,3-di-4-pyridyl-propane ligand displays a monodentate coordinating mode. In the crystal, there exist O-H⋯O, O-H⋯N and C-H⋯O hydrogen bonds. The perchlorate anions and the coordinated and lattice water mol-ecules play an important role in the formation of these hydrogen bonds. One of the two lattice water molecules shows half-occupancy.
