Crystal structure of tetra-phenyl phosphate tetra-kis-[dimethyl (2,2,2-tri-chloro-acet-yl)phos-pho-ramidato]lutetium(III), PPh[Lu].

A lutetium(III) complex based on the anion of the ligand dimethyl (2,2,2-tri-chloro-acet-yl)phospho-ramidate (H) and tetra-phenylphosphonium, of composition PPh[Lu ] ( = CAPh = carbacyl-amido-phosphate), or (CH)[Lu(CHClNOP)], has been synthesized and structurally characterized. The X-ray diffraction study of the compound revealed that the lutetium ion is surrounded by four bis-chelating CAPh ligands, forming the complex anion [Lu ] with a coordination number of 8[O] for Lu, while PPh serves as a counter-ion. The coordination geometry around the Lu ion was determined to be a nearly perfect triangular dodeca-hedron.

Tris{N-[bis(pyrrolidin-1-yl)phosphoryl]-2,2,2-trichloroacetamide}trichlorido-erbium(III).

The asymmetric unit of the title compound, [ErCl(3)(C(10)H(17)Cl(3)N(3)O(2)P)(3)], contains two independent mol-ecules. In each mol-ecule, the Er(III) ion is six-coordinated in a slightly distorted octa-hedral ErO(3)Cl(3) geometry with a fac-arrangement of the donor atoms. Intra-molecular N-H⋯Cl hydrogen bonds influence the mol-ecular conformations.

The title compound, [Na(2)(C(10)H(16)Cl(3)N(3)O(4)P)(2)(H(2)O)(2)](n), can be considered as a two-dimensional coordination polymer in which one-dimensional chains are connected to each other by inter-molecular C-H⋯O hydrogen bonds involving the water mol-ecules. The Na(I) ion is five-coordinated in a distorted trigonal-bipyramidal geometry. The connection between the two Na(I) ions is facilitated by the two μ-O atoms of the carbonyl group of the 2,2,2-trichloro-N-(dimorpholino-phosphor-yl)acetamide (CAPh) ligand.

catena-Poly[neodymium(III)-bis-[μ-N-(dimorpholinophosphor-yl)benzene-sulfonamidato]-sodium(I)-bis-[μ-N-(dimorpholinophosphor-yl)benzene-sulfonamidato]].

The cubic crystal structure of the title compound, [NaNd(C(14)H(21)N(3)O(5)PS)(4)](n), is composed of one-dimensional polymeric chains propagating in [100], built up from [Nd(C(14)H(21)N(3)O(5)PS)(4)](-) anions and sodium cations functioning as linkers. In the complex anion, the Nd(3+) ion has an eightfold coordination environment formed by the sulfonyl and phosphoryl O atoms of four bidentate chelating N-(dimorpholinophosphor-yl)benzene-sulfonamidate ligands: the resulting NdO(8) polyhedron can be described as inter-mediate between dodeca-hedral and square anti-prismatic. The sodium ion adopts an NaO(4) tetra-hedral geometry arising from four monodentate benzene-sulfonamidate ligands.

The crystal structure of the title compound, [U(NO(3))(2)O(2)(C(10)H(17)Cl(3)N(3)O(2)P)(2)], is composed of centrosymmetric [UO(2)(L)(2)(NO(3))(2)] mol-ecules {L is N-[bis-(pyrrolidin-1-yl)phosphor-yl]-2,2,2-trichloro-acetamide, C(10)H(17)Cl(3)N(3)O(2)P}. The U(VI) ion, located on an inversion center, is eight-coordinated with axial oxido ligands and six equatorial oxygen atoms of the phosphoryl and nitrate groups in a slightly distorted hexa-gonal-bipyramidal geometry. One of the pyrrolidine fragments in the ligand is disordered over two conformation (occupancy ratio 0.

In the title compound, C(16)H(17)Cl(3)N(3)O(2)P, the P atom has a slightly distorted tetra-hedral configuration. The conformations of the carbonyl and phosphoryl groups are anti to each other. In the crystal, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into infinite chains parallel to the b axis.

In the asymmetric unit of the crystal structure of the title compound, C(16)H(17)Cl(3)N(3)O(2)P, there are two crystallograph-ically independent mol-ecules, which form dimers via N-H⋯O hydrogen bonding between the N-H group and the P=O group. In the mol-ecular structure, the phosphoryl group is anti to the carbonyl group. The two benzene rings are oriented at dihedral angles of 54.
