In the title compound, [Mn(NCS)2(C15H14N2O4)(H2O)3]·2H2O, the metal ion is octa-hedrally coordinated by three water mol-ecules, one carboxyl-ate O atom from a 1,1'-(propane-1,3-di-yl)bis-(pyridinium-4-carboxyl-ate) ligand and two N atoms from two thio-cyanate anions in cis positions, forming a mononuclear complex mol-ecule. In the crystal, mol-ecules are connected into a three-dimensional architecture through O-H⋯O hydrogen bonds involving water mol-ecules and carboxyl-ate groups.
