Hexaaquanickel(II) 4,4′-(1,2-dihydroxyethane-1,2-diyl)dibenzoate monohydrate

Abstract

In the title compound, [Ni(H2O)6](C16H12O6)·H2O, the NiII cation is located on a mirror plane and is coordinated by six water molecules, two of which are also located on the mirror plane, in a distorted octahedral geometry. The 4,4′-(1,2-dihydroxyethane-1,2-diyl)dibenzoate anion is centrosymmetric with the mid-point of the central ethane C—C bond located on an inversion center. The uncoordinated water molecule is located on a mirror plane. Extensive O—H...O hydrogen bonding is present in the crystal structure.
