Hexakis(1H-imidazole-κN 3)mangan­ese(II) triaqua­tris(1H-imidazole-κN 3)manganese(II) bis­(naphthalene-14-dicarboxyl­ate)

摘要

In the crystal structure of the title compound, [Mn(C3H4N2)6][Mn(C3H4N2)3(H2O)3](C12H6O4)2, there are uncoordinated naphthalene­dicarboxyl­ate dianions and two kinds of Mn^II complex cations, both assuming a distorted octa­hedral geometry. One Mn^II cation is located on an inversion center and is coordinated by six imidazole mol­ecules, while the other Mn^II cation is located on a twofold rotation axis and is coordinated by three water mol­ecules and three imidazole units. The naphthalene­dicarboxyl­ate dianions are linked to both Mn^II complex cations via O—H⋯O and N—H⋯O hydrogen bonding, but no π–π stacking is observed between aromatic rings in the crystal structure.
