The complex [La(NO 3)3(TBMA)2] (TBMA = N,N,N’,N’-tetrabutylmalonamide) was prepared by the extraction method and characterized by single-crystal X-ray diffraction. The complex consists of two bidentate TBMA extractant and three bidentate nitrate ions coordinated to a La3+ ion. The lanthanum(III) is 10-coordinate, being bonded to four oxygen atoms of the malonamides and six oxygen atoms of the three nitrates. The crystal data are as follows C38H76N7O13La, Mr = 977.97, triclinic system, space group P 1, a = 1.3025(12), b = 1.4353(14), c = 0.4871(13) nm, α = 70.025(17), ß = 71.411(19), γ = 84.017(18)º, V = 2.476(4) nm3, Z = 2, F(000) = 1028, D = 1.312 g.cm-3, R 1 = 0.0833, wR 2 = 0.1471.
