A novel ionic compound [Fe(CN)6(phCH2NC5H5)3]·(H2O)4(Mr = 794.71) has been synthesized and its structure was characterized by IR, elemental analysis and X-ray diffraction. The compound crystallizes in monoclinic, space group P21/c with a = 10.837(2), b = 16.551(3), c = 23.402(5) , β = 97.531(4)o, V = 4161.0(15) A3, Z = 4, Dc = 1.269 g/cm3, F(000) = 1668, μ = 0.414 mm-1, R = 0.0479 and wR = 0.1232. The building unit of the title compound consists of three (phCH2N+C5H5) ions, one [Fe(CN)6]3- anion and four water molecules. According to the structural analysis, [Fe(CN)6]3- are linked together by O–H···N and O–H···O hydrogen bonds, but [Fe(CN)6]3- and [(phCH2N+C5H5)3] ions are bound by electrostatic force to form an ionic compound. 相似文献
