Abstract:

The asymmetric unit of the title compound, [MnI(C(24)H(16)N(6))(H(2)O)(2)]I·H(2)O, consists of a cationic Mn(II) complex, an I(-) anion and a solvent water mol-ecule. In the complex, the Mn(II) ion is six-coordinated in a considerably distorted octa-hedral environment defined by three N atoms of the tridentate 2,3,5,6-tetra-2-pyridyl-pyrazine (tppz) ligand, one I(-) anion and two O atoms of two water ligands. The dihedral angles between the pyridyl rings [maximum deviation = 0.034 (6) Å] and their carrier pyrazine ring [maximum deviation = 0.020 (6) Å] are 26.5 (2) and 27.0 (2)° for the coordinated pyridyl rings, and 51.3 (3) and 43.2 (2)° for the uncoordinated pyridyl rings. Inter-molecular O-H⋯O, O-H⋯N and O-H⋯I hydrogen bonds stabilize the crystal structure.
