Aqua-(4-nitro-phthalato-?O)bis-[2-(1H-pyrazol-3-yl-?N)pyridine-?N]-mangan-ese(II) hemihydrate.

ABSTRACT: In the title compound, [Mn(C(8)H(3)NO(6))(C(8)H(7)N(3))(2)(H(2)O)]·0.5H(2)O, the Mn(2+) ion is octa-hedrally coordinated by two 2-(1H-pyrazol-3-yl)pyridine ligands, one 4-nitro-phthalate ligand and one coordinated water mol-ecule leading to an overall MnN(4)O(2) coordination environment. The two 2-(1H-pyrazol-3-yl)pyridine ligands, which deviate from planarity by 0.0187?(2) and 0.0601?(2)?Å, make a dihedral angle of 81.90?(6)°. An intra-molecular N-H?O hydrogen bond occurs. Inter-molecular ?-? stacking inter-actions with a face-to-face separation of 3.61?(1)?Å between the 2-(1H-pyrazol-3-yl)pyridine ligands is observed. Additionally, O-H?O hydrogen bonding involving the uncoordinated water (which is situated on an inversion center), coordinated water mol-ecules and 2-(1H-pyrazol-3-yl)pyridine ligands leads to a three-dimensional network in the crystal structure.
