摘要：
The title compound [La(NO3)(6){Cu(2,2'-bipy)(2)}(2)][La(NO3)(6)Cu(2,2'-bipy)(2)]. CH3CN was synthesized, the crystal and molecular structures were determined at room temperature. The complex formed monoclinic crystals, space group P2(1)/n(No.14),, a = 10.354 (3) Angstrom, b = 23.440 (9) Angstrom, c = 32.811 (9) Angstrom, beta = 90.39 (2)degrees, Z = 4. The crystal structure consisted of a discrete [La(NO3)(6){Cu(2,2'-bipy)(2)}(2)](-) cation and [La(NO3)(6)Cu(2,2'-bipy)(2)](-) anion and a non-coordinated CH3CN molecule. Each La(III) ion was 12-coordinate with twelve oxygen atoms from six chelating nitrate ligands. There were four modes of nitrate coordination and the coordination geometry of all three copper ions was different in the crystal structure.
