Tetraaqua(1,10-phenanthroline)nickel(II) 3,6-dicarboxybicyclo[2.2.2]oct-7-ene-2,5-dicarboxylate

Abstract

In the title compound, [Ni(C12H8N2)(H2O)4](C12H10O8), the NiII ion is six-coordinated by two N atoms from one phenanthroline ligand and by the O atoms of four water molecules in a distorted octahedral geometry. In the crystal, intermolecular O—H...O hydrogen bonds form an extensive three-dimensional network, which consolidates the crystal packing.
