Abstract: The title compound, [Ni2(C7H3NO4)2(H2O)5]·2H2O, was obtained by the reaction of nickel iodide with dipicolinic acid (pyridine-2,6-dicarboxylic acid) and 1,10-phenanthroline (molar ratio 1:1:1) in EtOH/H2O. The compound contains two six-coordinated NiII ions, which are linked by two O atoms of the same carboxyl group from dipicolinic acid [Ni-O 2.179 (3) and 2.038 (3) Å]. Molecules are connected by van der Waals interactions.
