cis-Dichloridobis(1,10-phenanthroline-κ2 N,N′)manganese(II)–2,6-dihydroxy­benzoic acid–water (2/1/4)

摘要

In the crystal structure of the title compound, [MnCl2(C12H8N2)2]·0.5C7H6O4·2H2O, the Mn^II complex assumes a distorted octa­hedral geometry formed by two chloride anions and two phenanthroline (phen) ligands. The 2,6-dihydroxy­benzoic acid mol­ecule is disordered about an inversion center. The face-to-face separations of 3.540 (11) and 3.429 (8) Å between parallel phen ligands indicate the existence of π–π stacking between adjacent Mn^II complexes. Uncoordinated water mol­ecules are linked with complex and dihydroxy­benzoic acid mol­ecules via O—H⋯Cl and O—H⋯O hydrogen bonds.
