A new nickel citrate compound Ni(Hcit)(phen)(HO)·3HO (Hcit = citrate acid, phen = 1,10-phenanthroline) has been synthesized and characterized by single-crystal X-ray diffraction.It crystallizes in the trigonal system, space group P3 with a = 13.8319(13), c= 10.425(2) (A), V= 1727.3(4) (A), Mr=501.09, F(000) = 780,μ=0.901 mm cation is chelated by a phen molecule, one Hcit center through three functional groups: α-hydroxyl, α-carboxylate and β-carboxylate while another α-carboxylate forms hydrogen bond with surrounding HO molecule.And the citric acid is doubly protonated.The temperature-dependent magnetic susceptibility data revealed that the compound is a paramagnetic material.
