Tetraaqua(1,10-phenanthroline-N,N)nickel(II) dinitrate monohydrate

Abstract

The title compound, [Ni(C 12 H 8 N 2 )(H 2 O) 4 ](NO 3 ) 2 .H 2 O, consists of tetraaqua(1,10-phenanthroline)nickel (II) cations, nitrate anions and water molecules. The Ni II ion is coordinated in a distorted octahedral arrangement by two water molecules and two tertiary N atoms from one phenanthroline ligand in equatorial positions, and by two O atoms of water in axial positions. The Ni-O bond lengths range from 2.053 (2) to 2.105 (2) A and the two Ni-N bond lengths are 2.068 (2) and 2.070 (2) A, while the N1-Ni-N2 chelate angle is 80.83 (8)°. The complex forms a three-dimensional hydrogen-bonded framework.
