Bis{N-[bis­(pyrrolidin-1-yl)phosphor­yl]-2,2,2-trichloro­acetamide}di­nitrato­dioxidouranium(VI)

The crystal structure of the title compound, [U(NO3)2O2(C10H17Cl3N3O2P)2], is composed of centrosymmetric [UO2(L)2(NO3)2] mol­ecules {L is N-[bis­(pyrrolidin-1-yl)phosphor­yl]-2,2,2-trichloro­acetamide, C10H17Cl3N3O2P}. The UVI 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 hexa­gonal-bipyramidal geometry. One of the pyrrolidine fragments in the ligand is disordered over two conformation (occupancy ratio 0.58:0.42). Intra­molecular N—H⋯O hydrogen bonds between the amine and nitrate groups are found

Tris{N-[bis­(dimethyl­amino)phosphino­yl]-2,2,2-trichloro­acetamido}(triphenyl­phosphine oxide)holmium(III)

In the title compound, [Ho(C6H12Cl3N3O2P)3(C18H15OP)], the HoIII ion is surrounded by six O atoms from the three bidentate N-[bis­(dimethyl­amino)phosphino­yl]-2,2,2-trichloro­acetamido ligands (L −) and by one O atom from the triphenyl­phosphine oxide ligand, with the formation of a distorted monocapped octa­hedron. In one ligand L −, the trichloro­methyl group is rotationally disordered between two orientations in a 1:1 ratio, while two dimethyl­amino groups in another ligand L − are disordered between two conformations, each with the same 1:1 ratio

N-[Bis(dimethyl­amino)phosphinoyl]-2,2,2-trichloro­acetamide

In the title compound, C6H13Cl3N3O2P or CCl3C(O)NHP(O)(N(CH3)2), the phosphinoyl group is synclinal to the carbonyl group and acts as an acceptor for an inter­molecular N—H⋯O hydrogen bond from the amide group as the donor

{Dimethyl [(phenylsulfonyl)amido]phosphato-κ2O,O′}bis(triphenylphosphane-κP)copper(I)

In the title complex, [Cu(C8H11NO5PS)(C18H15P)2], the CuI ion is coordinated by two triphenylphosphane molecules and two O atoms of the chelating dimethyl(phenylsulfonyl)amidophosphate anion, generating a squashed CuO2P2 tetrahedron. In the six-membered chelate ring, the Cu, P and O atoms are almost coplanar (r.m.s. deviation = 0.024 Å), with the N and S atoms displaced in the same direction, by 0.708 (5) and 0.429 (2) Å, respectively

Crystal structure of {μ-6,6′-dimethoxy-2,2′-[ethane-1,2-diylbis(nitrilomethanylylidene)]diphenolato}(methanol)(nitrato)nickel(II)sodium

In the molecular structure of the title compound, [NaNi(C18H18N2O4)(NO3)(CH3OH)], the Ni2+ ion has a slightly distorted square-planar coordination environment defined by two N and two O atoms which belong to a Schiff base ligand, viz. 6,6′-dimethoxy-2,2′-[ethane-1,2-diylbis(nitrilomethanylylidene)]diphenolate. Seven O atoms form the coordination environment of the Na+ ion: four from the Schiff base ligand, two from a bidentate chelating nitrate anion and one O atom from a coordinating methanol molecule. In the crystal, the bimetallic complexes are assembled into chains along the b-axis direction via weak C—H...O hydrogen-bond interactions. Neighbouring chains are in turn connected through bifurcated O—H...O hydrogen bonds that involve the coordinating methanol molecules and the nitrate anions, and through π–π stacking interactions between phenyl rings of neighbouring molecules
