Tris(4-formyl-phen-yl)phosphane oxide tetra-hydro-furan hemisolvate.

ABSTRACT: The title compound, C21H15O4P·0.5C4H8O, contains an ordered phosphane oxide in a general position and a tetra-hydro-furan solvent mol-ecule disordered about a twofold axis. All three aldehyde substituents are nearly coplanar with their attached benzene rings, with C-C-C-O torsion angles in the range 1.64?(17)-4.24?(19)°. All three have different conformations with respect to the P=O group, one syn, one anti, and one gauche. Two of the aldehyde substituents form inter-molecular C-H?O contacts.

Project description:The asymmetric unit of the title crystal, [FeCl(2)(C(3)H(9)P)(3)(CO)]·[FeCl(2)(C(3)H(9)P)(2)(CO)(2)]·2C(4)H(8)O, contains half mol-ecules of the two closely related Fe(II) complexes lying on mirror planes and a tetra-hydro-furan solvent mol-ecule, one C atom of which is disordered over two sets of sites with site occupancy factors 0.633 (9) and 0.367 (9). In both Fe(II) complex mol-ecules, a distorted octa-hedral coordination geometry has been observed around the Fe atoms. Weak intermolecular C-H⋯O inter-actions are observed in the crystal structure.

trans-Tetra-carbonyl-bis-[tris-(3-fluoro-phen-yl)phosphane]chromium(0).

Project description:In the title compound, [Cr(C(18)H(12)F(3)P)(2)(CO)(4)], the Cr atom is octa-hedrally coordinated by four carbonyl ligands and the two tertiary phosphanes, which are trans to each other. The three benzene rings in one phosphane ligand make dihedral angles of 53.50?(9), 75.51?(10) and 80.63?(10)° with each other, while in the other ligand these angles are 51.92?(10), 78.56?(11) and 86.80?(10)°. C-H?O and C-H?F inter-actions link the mol-ecules into a three-dimensional network. Each of the F atoms is disordered over two positions with refined occupancies of 0.944?(3):0.056?(3), 0.702?(4):0.298?(4), 0.829?(4):0.171?(4), 0.567?(4):0.433?(4), 0.545?(4):0.455?(4) and 0.920?(4):0.080?(4).

trans-Tetra-carbonyl-bis-[tris-(4-fluoro-phen-yl)phosphane-κP]chromium(0).

Project description:In the title compound, [Cr(C(18)H(12)F(3)P)(2)(CO)(4)], the Cr atom is octa-hedrally coordinated by four carbonyl ligands and the two tertiary phosphanes that are trans to each other. The Cr atom and two carbonyl groups are on a twofold axis. The benzene rings attached to the phospho-rus atom make dihedral angles of 80.32 (5), 52.91 (5) and 83.80 (5)° with each other. In the crystal, C-H⋯O and C-H⋯F inter-molecular inter-actions form an infinite three-dimensional network.

[(2R,3S,5R)-3-Acet-oxy-5-(5-formyl-2,4-dioxo-1,2,3,4-tetra-hydro-pyrimidin-1-yl)-2,3,4,5-tetra-hydro-furan-2-yl]methyl acetate.

Project description:In the two independent but very similar mol-ecules (A and B) of the title compound, C(14)H(16)N(2)O(8), both six-membered pyrimidine rings are nearly planar [maximum deviations = 0.010?(3)?Å in A and 0.028?(3)?Å in B]. The five-membered furan-ose ring in mol-ecule A adopts an envelope conformation, while the same ring in mol-ecule B has a twisted conformation. In the crystal, the A mol-ecules are linked via a pair of inter-molecular N-H?O hydrogen bonds, forming dimers. Each A mol-ecule is further linked to a B mol-ecule via a second N-H?O hydrogen bond. There are also a number of C-H?·O inter-actions present, leading to the formation of a three-dimensional network.

Bis{μ4-N-[phen-yl(pyridin-2-yl-aza-nid-yl)meth-yl]pyridin-2-aminido}tetra-kis(tetra-hydro-furan)-tetra-lithium.

Project description:The title complex, [Li4(C17H14N4)2(C4H8O)4], bears a novel tetra-dentate di-amido ligand. In the tetra-nuclear centrosymmetric complex mol-ecule, the metal atoms exhibit two kinds of coordination modes. The middle two Li(+) cations are coord-inated by four N (ligand) and one O (tetra-hydro-furan, THF) atoms, resulting in a distorted square-pyramidal geometry. The outer two Li(+) cations are in distorted tetra-hedral environments consisting of three N (ligand) and one O (THF) atoms. The Li-N bond lengths vary from 2.020 (7) to 2.441 (6)Å.
