| 英文摘要 | A new dinuclear centrosymmetric complex [LaL(HL)(H2O)(3)](2)(.)2H(2)O (H2L = 3-nitrophthalic acid, NPA) was synthesized in water/ethanol solution and characterized by X-ray diffraction, IR spectrum and TGA-DTA. The complex crystallizes in triclinic system, space group P-1(-) with a = 8.1549(16), b = 8.8856(18), c = 15.277(3) angstrom, alpha= 100.93(3), beta = 90.81(3), gamma = 104.56(3)degrees, V = 1049.8(4) angstrom(3), Z = 1, mu = 2.125 mm(-1), D-c 1.994 g/cm(3), R = 0.0259 and wR = C.0679. Two 3-nitrophthalates(2-) coordinate with the La3+ ions in a bridging mode, and two monohydrogen-3-nitrophthates(1-) and three waters in terminal ways, respectively. Each La3+ ion is nine-coordinated to exhibit a distorted tricapped trigonal prism coordination polyhedron. Both the coordinated and crystal waters are involved in the inter- and intramolecular hydrogen bonds. The dinuclear units are linked into a 2D network structure in the ab plane via intermolecular hydrogen bonds along the axes a and b. Two crystal waters fill each rhombic pore of the network. The networks are further packed along the c axis forming a layered supramolecular structure through the C-(HO)-O-... weak forces between the adjacent sheets. TGA analysis shows the complex undergoes the loss of waters of crystallization and coordination and the decomposition of ligands sequentially. |
