A Novel Layered Supramolecular Network Constructed from Heterohexanuclear La(Ⅲ)-Cr(Ⅲ) Complexes by Hydrogen Bonding

         

摘要

The complex [La2(-ox){Cr(bipy)((μ-ox)(ox)}4(H2O)6]·12.3(H2O) (C58H68.6N8O54.3Cr4La)2 1 has been obtained from the reaction of La(Ⅲ) salt with [Cr(bipy)(ox)2]-(bipy = 2,2'-bipyridine and ox = oxalate dianion)building blocks in aqueous solution and structurally characterized by X-ray diffraction analysis. It crystallizes in monoclinic, space group P21/c with a = 10.740(2), b = 17.943(4), c = 22.388(5)A, V = 4314(2)A3, Z = 2, Mr = 2232.4(3), Dc = 1.719 g/cm3, F000 = 2234, (MoK = 1.565 cm-1 and T = 2932 K. With the use of 5202 observed reflections(I>2σ(I), the structure was refined to R = 0.0742 and wR = 0.1554. Complex 1 shows a two-dimensional open network constructed from hexanuclear {La2Cr4} units through the intermolecular hydrogen interactions.
