Trimethyl-3-meth-oxy-4-oxo-5-triphenyl-phospho-ranyl-idene-cyclo-pent-1-ene-1,2,3-tricarboxyl-ate.

ABSTRACT: The title compound, C(30)H(27)O(8)P (2), was formed as one of two products {(1) [Krawczyk et al. (2010 ?). Acta Cryst. E66 (cv2752)] and (2)} in the reaction of dimethyl acetyl-enedicarboxyl-ate with triphenyl-phosphine. The mol-ecule of (2) consists of a five-membered carbocyclic ring. The P atom is a part of a triphenylphosphoranylidene substituent. In contrast to (1), the five-membered ring of (2) is planar, the r.m.s. deviation being only 0.009?(2)?Å.

4-Acetamido-N-(?-triphenyl-phospho-ranyl-idene)benzene-sulfonamide.

Project description:There are two independent mol-ecules per asymmetric unit of the title compound, C(26)H(23)N(2)O(3)PS. Their superposition shows that they differ in the conformation of the CH(3)CO- group and the benzene rings from the triphenyl-phospho-rane group. In the crystal structure, independent mol-ecules are inter-conected by strong N-H?O hydrogen bonds, forming infinite chains along the a axis.

Bis(triphenyl-phospho-ranyl-idene)ammonium iodide.

Project description:The title compound, C(36)H(30)NP(2) (+)·I(-), was obtained accidently from crystallization of a reaction mixture containing [(Ph(3)P)(2)N]OH and B(OH)(3), which was contaminated with MeI. There are two independent [(Ph(3)P)(2)N](+) cations and two I(-) anions within the asymmetric unit. The central PNP angles are non-linear [137.6?(2) and 134.4?(2)°] and the phenyl substituents on P centres adopt different conformations within these two cations.

(5-Ammonio-pent-yl)triphenyl-phospho-nium dibromide ethanol solvate.

Project description:The alkyl-ammonium chain of the dication in the title mitochondrially targeted (5-ammonio-pent-yl)triphenyl--phos-pho-nium dibromide ethanol solvate, C(23)H(28)NP(2+)·2Br(-)·C(2)H(6)O, is almost planar (r.m.s deviation = 0.0716?Å for all non-H atoms) and in the extended form, maximizing the P?N distance [7.716?(2)?Å]. The ions and solvent are linked within the crystal by N-H?Br, N-H?O and O-H?Br hydrogen-bonding inter-actions, forming C(3) (2)(6) chains along the b axis, with secondary C-H?Br and C-H?O inter-actions cross-linking the chains.

Trimethyl 5-(2-chloro-4-fluoro-phen-yl)-2-phenyl-pyrrolidine-2,3,4-tricarboxyl-ate.

Project description:The title compound, C(22)H(21)ClFNO(6), was synthesized by the 1,3-dipolar cyclo-addition reaction of dimethyl maleate, methyl 2-amino-2-phenyl-acetate and 2-chloro-4-fluoro-benzaldehyde. The pyrrolidine ring possesses an envelope conformation and the two benzene rings are oriented at a dihedral angle of 68.28?(7)°. Weak inter-molecular C-H?O hydrogen bonding is present in the crystal structure. One methyl group is disordered over two positions with a site-occupancy ratio of 0.651?(12):0.349?(12).

(2,5-Diphenyl-pent-4-yn-1-en-3-yl-idene)triphenyl-phospho-rane.

Project description:The title compound, C(45)H(27)P, was obtained as a product of the reaction of triphenyl-methyl-enephospho-rane with one molar equivalent of 1,4-diphenyl-butadiyne in toluene. The compound was very stable under ambient conditions, but rapidly decomposed in solution when exposed to the air. The P atom is tetra-coordinated in an approximately tetrahedral geometry. The length of the C C triple bond [1.206?(2)?Å] is in the normal range.

catena-Poly[[chlorido[1-(3-nitro-phen-yl)-2-(triphenyl-phospho-ranyl-idene)ethanone-?C(2)]mercury(II)]-?-chlorido].

Project description:In the title organometallic polymer, [HgCl(2)(C(26)H(20)NO(3)P)](n), the monodentate 1-(3-nitro-phen-yl)-2-(triphenyl-phospho-ran-yl--idene)ethanone ligand is coordinated to the Hg(II) atom through the methine C atom. The Hg(II) atom is four-coordinated in a distorted tetra-hedral geometry by one terminal Cl atom, two bridging Cl atoms, and one C atom from the ylidic ligand, resulting in a polymeric chain parallel to [010]. The terminal Cl atom is more strongly bound to the Hg(II) ion [2.3916?(9)?Å] than the bridging Cl atoms. The bridge is asymmetric, as indicated by the two different Hg-Cl(bridging) bond lengths [2.5840?(8) and 2.7876?(8)?Å]. Intra-molecular C-H?O and weak C-H?Cl contacts stabilize the polymeric chain. In the crystal, adjacent chains inter-act via C-H?O hydrogen bonds.

Inversion dimers dominate the crystal packing in the structure of trimethyl citrate (trimethyl 2-hy-droxy-propane-1,2,3-tri-carboxyl-ate).

Project description:Trimethyl citrate, C9H14O7 (systematic name: trimethyl 2-hy-droxy-propane-1,2,3-tri-carboxyl-ate), 2, was prepared by the esterification of citric acid and methanol in the presence of thionyl chloride at 273 K. The bond lengths and angles in 2 compare closely with those observed in citric acid. The C-C bonds adjacent to the terminal carboxyl groups are significantly shorter than those around the central C atom. The central carboxyl-ate group and the hy-droxy group occur in the normal planar arrangement with an r.m.s. deviation of 0.0171 Å from the mean plane involving all six atoms in the central unit. The crystal structure is almost completely dominated by the formation of inversion dimers through an O-H⋯O hydrogen bond, together with an extensive array of weaker C-H⋯O contacts. These generate a three-dimensional network structure with mol-ecules stacked along the c-axis direction.

Ethyl 2,7,7-trimethyl-5-oxo-4-phenyl-1,4,5,6,7,8-hexa-hydro-quinoline-3-carboxyl-ate.

Project description:In the title compound, C(21)H(25)NO(3), the hydro-pyridine ring that constitutes a part of the hexa-hydro-quinoline fused-ring system adopts a sofa conformation; the methine C atom deviates from the least-squares plane defined by the remaining five non-H atoms (r.m.s. deviation = 0.088?Å) by 0.454?(3)?Å. The phenyl ring is aligned at 85.5?(1)° with respect to this mean plane. In the crystal, adjacent molecules are linked via an N-H?O hydrogen bond, involving the amino group and the carbonyl O atom of the fused-ring system, forming chains running along [100]. The ethyl group is disordered over two positions in a 0.609?(6):0.391?(6) ratio.

Project description:In the title complex, [Hg(2)I(4)(C(26)H(20)FOP)(2)], the Hg(II) centre is four-coordinate with one short Hg-I bond [2.6895 (7) Å], one Hg-C bond and two asymmetric bridging Hg-I bonds with distances of 2.7780 (8) and 3.2599 (8) Å. The title mol-ecule has a crystallographic inversion centre at the centroid of the four-membered ring formed by the two Hg atoms and two I atoms. The crystal packing is stabilized by C-H⋯O hydrogen bonds.

Benzyl-triphenyl-phospho-nium dichlorido-triphenyl-stannate(IV).

Project description:The crystal structure of the title salt, (C25H22P)[Sn(C6H5)3Cl2] or (PhCH2PPh3)[SnPh3Cl2], consists of [PhCH2PPh3](+) cations and [SnPh3Cl2](-) anions in which the Sn(IV) atom is linked to two Cl atoms and three phenyl groups in a trigonal-bipyramidal geometry, with the Cl atoms in trans positions. The cation adopts a tetra-hedral geometry. In the crystal, the cations and the anions are connected by C-H?Cl hydrogen bonds, leading to an infinite chain propagating along the c direction.
