The complex 2 Complex $$$$ LI Xia *, JIN Qiong Hua (Department of Chemistry,Capital Normal University,Beijing 100037) Abstract The complex [Nd(C 4 H 3 OCOO) 2 ·NO 3 ·C 10 H 8 N 2 ] 2 was synthesized from Nd(NO 3 ) 3 · n H 2 O, 2 furancarboxylic acid(C 4 H 3 OCOOH), and 2,2′ bipyridine(C 10 H 8 N 2 ). The unit cell is triclinic and of Pī symmetry. Unit cell parameters are:Pī, a =0 992 18(17) nm, b =1 023 05(17) nm, c = 1 114 4(3) nm , α =86 778(8)°, β =76 153(5)°, γ =70 363(14)°, M =584 58, V = 1 037 3(4) nm 3 , Z =1 , D calc = 1 877 Mg/m 3 , T =293(2) K. The final R =0 061 8, w R =0 164 4. Each Nd 3+ ion is coordinated by five O atoms of four furancarboxylate groups, two O atoms of nitrate and two N atoms of 2,2′ bipyridine molecule, with a coordination number of 9. The four carboxylate groups coordinate in two modes:bridging and bridging chelating . The two Nd 3+ ions in the dimer are held together by four carboxylate groups of furancarboxylic acid.
