| Abstract: | The title complex Nd(o-NO2-C6H4COO)3(DMF)2]2 has been synthesized by the reaction of Nd(NO3)3 ?nH2O with o-nitrobenzoic acid (C7H5O4N) and N,N-dimethylformamide (DMF). The complex resides on an inversion center. The structure of the complex was characterized by the method of IR, 1H NMR, UV, elemental analysis, fluorescent emission spectroscopy and X-ray single crystal diffraction. The results show that the complex crystallizes in a triclinic system, space group P-1 with cell parameters a＝1.18652(12) nm, b＝1.24784(13) nm, c＝1.29958(13) nm, α＝64.220 (1)°, β＝66.306 (1)°, γ＝71.825 (1)°, V＝1.5645 (3) nm3, Dc＝2.167 mg/m3, Z＝2, μ＝3.415 mm－1 and F(000)＝986. Each Nd(III) atom is bridged by four o-nitrobenzoates and chelated by one o-nitrobenzoate. The Nd(III) atom is eight-coordinated by six oxygen atoms from five o-nitrobenzoates and two oxygen atoms from two DMF molecules. Hydrogen bonds and aromatic π…π stacking interactions assemble the title complex into a three dimensional network. Luminescence measurement shows that the complex emits fluorescence. |
