摘要
The complex [La2(μ-ox){Cr(bipy)(μ-ox)(ox)} 4(H2O)6]-12.3(H2O) (C 58H68.6NgO54.3Cr4La2) 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 P2 1/c with a = 10.740(2), b = 17.943(4), c = 22.388(5) Å, V = 4314(2) Å3, Z = 2, Mr = 2232.43, Dc = 1.719 g/cm3, F(000) = 2234, μ(MoKα) = 1.565 cm-1 and T = 293(2) 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 {La2Cr 4} units through the intermolecular hydrogen interactions.
