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

ABSTRACT: 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.

(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.

Crystal structure of (E)-1-(2,4-di-nitro-phen-yl)-2-[(E)-5-phenyl-1-(p-tol-yl)pent-2-en-4-yn-1-yl-idene]hydrazine.

Project description:In the title compound, C24H18N4O4, the plane of the phenyl ring is inclined to those of the toluene ring and the di-nitro-substituted benzene ring by 66.96?(19) and 47.06?(18)°, respectively, while the planes of the two benzene rings are inclined to one another by 36.26?(19)°. There is an intra-molecular N-H?O hydrogen bond between the NH group and the O atom of a nitro group, forming an S(6) ring motif. In the crystal, mol-ecules are linked by C-H?O hydrogen bonds and C-H?? inter-actions, forming a three-dimensional network. There are also weak ?-? inter-actions present involving the phenyl ring and the di-nitro-substituted benzene ring [inter-centroid distance = 3.741?(2)?Å].

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

Project description: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.

Carbon-yl[4-(2,3-dimethyl-phenyl-amino)pent-3-en-2-onato-?N,O](triphenyl-phosphine-?P)rhodium(I).

Project description:In the title compound, [Rh(C(13)H(16)NO)(C(18)H(15)P)(CO)], the coordination geometry of the Rh(I) atom is square-planar, formed by the coordinating N and O atoms of the bidentate enaminoketonate ligand, one C atom from the carbonyl group and a P atom from triphenyl-phosphine. The complex displays a 0.591?(3):0.409?(3) ratio disorder of the phenyl unit of the monoanionic N,O-bidentate ligand. Intra-molecular hydrogen bonding is observed between a C-H group of the triphenyl-phosphine unit and the O atom of the enamino-ketonate ligand.

(Cyano-meth-yl)triphenyl-phospho-nium chloride.

Project description:In the mol-ecule of the title compound, C(20)H(17)NP(+)·Cl(-), the coordination around the P atom is slightly distorted tetra-hedral.

(Z)-4-(2,5-Di-tert-butyl-anilino)pent-3-en-2-one.

Project description:In the crystal structure of the title ketoamine, C(19)H(29)NO, the bond lengths from the N atom through the alkene group to the ketone O atom show the presence of an extensively delocalized ?-system. The dihedral angle between the plane of the phenyl ring and that of the alkene component is 63.45?(7)° due to steric hindrance exerted by the tert-butyl groups. The mol-ecule has a Z-configured alkene function, which is facilitated by an intra-molecular N-H?O hydrogen bond between the amine and ketone groups. The mol-ecules are linked into extended chains, which run parallel to the [010] direction, by a very weak C-H?O inter-action between the methyl substituent of the alkene group and the ketone O atom of a neighbouring mol-ecule.
