Abstract

The complex [La₂(μ-ox){Cr(bipy)(μ-ox)(ox)} ₄(H₂O)₆]-12.3(H₂O) (C ₅₈H_68.6NgO_54.3Cr₄La₂) 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, M_r = 2232.43, D_c = 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.
