Aqua­(2,6-dihy­droxy­benzoato-κO¹)bis­(1,10-phenanthroline-κ²N,N′)manganese(II) 2,6-dihy­droxy­benzoate hemihydrate

In the complex cation of the title compound, [Mn(C₇H₅O₄)(C₁₂H₈N₂)₂(H₂O)](C₇H₅O₄)·0.5H₂O, the Mn^II atom has a six-coordinate octa­hedral environment defined by one carboxyl­ate O atom belonging to a 2,6-dihy­droxy­benzoate (DHB) ligand, four N atoms from two chelating 1,10-phenanthroline mol­ecules and one water mol­ecule. The lattice water mol­ecule lies on a twofold rotation axis. Intra­molecular O—H...O hydrogen bonds are present in the DHB anions and complex cations. Inter­molecular O—H...O hydrogen bonds link two cations, two anions and one water mol­ecule into a dimer. π–π inter­actions between the pyridine and benzene rings and between the benzene rings are also observed [centroid–centroid distances = 3.7774 (16), 3.7912 (16) and 3.7310 (17) Å].
