| 中文摘要 | A new dinuclear La(III) complex [La-2(4-cba)(4)[H(4-cba)(2)](2)(phen)(2)(H2O)(4)] (4-Hcba = 4-cyanobenzoic acid and phen = 1,10-phenanthroline) l has been synthesized by solvothermal reaction in an ethanol/water mixed solution at 100 V and structurally characterized by single-crystal X-ray diffraction. Crystallographic data: C88H58La2N12O20, M-r = 1881.28, triclinic P1, a = 7.518(3), b = 17.033(6), c = 17.551(6) angstrom, alpha = 115.333(4), beta = 92.9910(10), gamma = 99.366(5)degrees, V= 1985.3(12) angstrom(3), Z = 1, D-c= 1.574 g/cm(3), F(000) = 944 mu = 1.145 mm(-1), the final R = 0.0281 and wR 0.0686 for 6708 reflections with I > 2 sigma(I). In 1, two nine-coordinated La(III) ions are connected by two 4-cba ligands in a syn-syn bidentate coordination mode, and the other six 4-cba ligands terminate the La(III) ions, resulting in an isolated dinuclear structure. Two different types of intramolecular hydrogen bonds, asymmetrical O-H center dot center dot center dot O and symmetrical O center dot center dot center dot H center dot center dot center dot O, exist in the crystal. The title complex molecules are connected through hydrogen bonds and weak Pi-Pi stacking interactions to generate a 2-D layered network. The thermogravimetric analysis of 1 has also been discussed. |
