| Abstract: | The title compound La(NO3)6{Cu(2,2′-bipy)2}2]La(NO3)6Cu(2,2′-bipy)2] CH3CN was synthesized, the crystal and molecular structures were determined at room temperature. The complex formed monoclinic crystals, space group P21/n (No.14), a = 10.354 (3) A, b = 23.440 (9) A, c = 32.817 (9) A, b = 90.39 (2)°, Z = 4. The crystal structure consisted of a discrete La(NO3)6{Cu(2,2′-bipy)2}2]+ cation and La(NO3)6Cu(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. |
