摘要

In the title compound, [Mn(C8H3NO6)(C8H7N3)(2)(H2O)]center dot 0.5H(2)O, the Mn2+ ion is octahedrally coordinated by two 2( 1H-pyrazol-3-yl)pyridine ligands, one 4-nitrophthalate ligand and one coordinated water molecule leading to an overall MnN4O2 coordination environment. The two 2-(1H-pyrazol-3-yl)pyridine ligands, which deviate from planarity by 0.0187 (2) and 0.0601 (2) angstrom, make a dihedral angle of 81.90 (6)degrees. An intramolecular N-H center dot center dot center dot O hydrogen bond occurs. Intermolecular pi-pi stacking interactions with a face-to-face separation of 3.61 (1) angstrom between the 2-(1H-pyrazol-3-yl) pyridine ligands is observed. Additionally, O-H center dot center dot center dot O hydrogen bonding involving the uncoordinated water (which is situated on an inversion center), coordinated water molecules and 2-(1H-pyrazol-3-yl)pyridine ligands leads to a three-dimensional network in the crystal structure.
