A novel ionic complex of [Ni(phen)2(H2O)2][Ni(PDC)2]•7H2O was synthesized in aqueous solution (H2PDC＝pyridine-2,6-dicarboxylic acid; phen＝1,10-phenanthroline). Elemental analysis, IR spectroscopy, single X-ray diffraction and thermogravimetric analysis for the title complex are presented. Crystal data: triclinic, space group P1, a＝1.0092(4) nm, b＝1.4599(6) nm, c＝1.4933(5) nm, α＝73.982(2)°, β＝78.652(2)°, γ＝75.184(3)°, V＝2.0256(13) nm2, Z＝2, F(000)＝1004, μ＝1.014 mm－1, R1＝0.0538, wR2＝0.1493 [I＞2.00σ(I)]. It is very interesting that lattice water forms a cluster (H2O)12, which gives rise to a novel 2D water network through hydrogen bonding. Furthermore, the interactions among the 2D water networks lead to a 3D supramolecule.

Key words: ionic complex, pyridine-2,6-dicarboxylic acid, 1,10-phenanthroline, crystal structure
