Abstract The coordination compounds of the general formula Ln(HL)2(NO3)3, (where Ln = La - Eu (without Pm), HL = C6H5C(O)NHP(O)[N(CH3)2]2, N,Nʹ-tetramethyl-Nʺ-benzovlphosphoryl-triamide) have been synthesized and characterized by means of IR, UV-VIS, 1H, 31P NMR spectroscopy, and X-ray analysis. The complexes are isostructural according to X-ray powder diffraction studies. The crystal structure of the cerium(lll) complex has been determined. Crystal data: monoclinic, P21/c, with a = 10.503(9), b = 15.62(2), c = 21.91(2) Å, β = 99.56(8)°, Z = 4, V = 3546(6) Å3, R1= 0.0550, wR2 = 0.1383 for 6970 unique reflections used. The complex has a molecular structure. Neutral phosphoryltriamide ligands are coordinated to the metal ion in a bidentate manner via phosphoryl and carbonyl oxygen atoms with formation of six membered chelate rings. The coordination polyhedron of the Ce atom is a sphenocorona; C.N. = 10 (4 O[HL] + 6 O [NO3-]).
