摘 要:A new nickel citrate compound Ni(H2cit)(phen)(H2O).3H2O(H4cit = 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 P31 with a = 13.8319(13),c = 10.425(2),V = 1727.3(4)3,Dc = 1.445 g/cm3,Mr = 501.09,F(000) = 780,μ = 0.901 mm-1,Z = 3,R = 0.0760 and wR = 0.1730 for 3859 observed reflections(I 2σ(I)).In this compound,Ni2+ cation is chelated by a phen molecule,one H2cit2-anion and one H2O molecule.The citric acid coordinates to the Ni2+ center through three functional groups:α-hydroxyl,α-carboxylate and β-carboxylate while another α-carboxylate forms hydrogen bond with surrounding H2O molecule.And the citric acid is doubly protonated.The temperature-dependent magnetic susceptibility data revealed that the compound is a paramagnetic material.A new nickel citrate compound Ni(H2cit)(phen)(H2O).3H2O(H4cit = 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 P31 with a = 13.8319(13),c = 10.425(2),V = 1727.3(4)3,Dc = 1.445 g/cm3,Mr = 501.09,F(000) = 780,μ = 0.901 mm-1,Z = 3,R = 0.0760 and wR = 0.1730 for 3859 observed reflections(I 2σ(I)).In this compound,Ni2+ cation is chelated by a phen molecule,one H2cit2-anion and one H2O molecule.The citric acid coordinates to the Ni2+ center through three functional groups:α-hydroxyl,α-carboxylate and β-carboxylate while another α-carboxylate forms hydrogen bond with surrounding H2O molecule.And the citric acid is doubly protonated.The temperature-dependent magnetic susceptibility data revealed that the compound is a paramagnetic material.
