ABSTRACT: In the title compound, [Co(C(20)H(18)P)I(C(3)H(9)P)(2)], the Co(II) atom has a distorted square-pyramidal geometry, the base of which is comprised of two trans PMe(3) groups, an I atom, and a C atom of the benzyl group. This benzyl group is tethered to the P atom at the apex of the pyramid, thereby forming a five-membered chelated Co-C-C-C-P ring.
Project description:The title compound, [Fe(C(7)H(5)FN)Cl(C(3)H(9)P)(3)], was obtained as a product of the reaction of [Fe(Me(3)P)(4)] with a molar equivalent of (2-chloro-6-fluoro-phen-yl)methanimine in diethyl ether. This compound is sensitive to air, and rapidly decomposes when exposed to air for a few minutes. The Fe atom has an octa-hedral coordination geometry in which the bidentate fluoro-phenyl methanimine ligand forms the equatorial plane with the Cl atom and one of the trimethyl-phosphane ligands. The other two trimethyl-phosphane ligands are located in the axial positions. In the crystal, an N-H?Cl hydrogen bond occurs.
Project description:In the title complex, [CuCl(C8H8N2OS)(C18H15P)2]·2CH3OH, the Cu(I) ion is coordinated by one chloride anion, one S atom from the 5-meth-oxy-1H-benzimidazole-2(3H)-thione ligand and two P atoms from two tri-phenyl-phosphine ligands in a distorted tetra-hedral geometry. One of the N-bound H atoms is involved in an intra-molecular N-H⋯Cl hydrogen bond, while another one inter-acts with the solvent methanol mol-ecule via an N-H⋯O hydrogen bond. Inter-molecular O-H⋯Cl and O-H⋯O hydrogen bonds link two further complex mol-ecules and four solvent mol-ecules into a centrosymmetric structural unit. The short distance of 3.624 (4) Å between the centroids of the five- and the six-membered rings of two benzimidazole fragments indicates the presence of π-π inter-actions.
Project description:In the title compound, C21H17N2P, the dihedral angles between the 1,5-naphthyridine ring system (r.m.s. deviation = 0.005?Å) and the phenyl rings are 89.18?(8) and 77.39?(8)°. The phenyl rings are almost perpendicular, making a dihedral angle of 88.12?(8)°. The only possible inter-molecular inter-action is a very weak aromatic ?-? stacking inter-action [centroid-centroid separation = 3.898?(2)?Å].
Project description:The title compound, [Co(C(27)H(25)O(2)P(2))I(C(3)H(9)P)], was synthesized by the addition of 1-iodo-butane to a solution of the parent cobalt complex {1,3-bis-[(diphenyl-phosphan-yl)-oxy]prop-2-yl}bis-(trimethyl-phosphane)cobalt(II). Two five-membered cobaltocycles with considerable ring bending (sum of inter-nal angles = 516.4 and 517.7°) are formed through two P atoms of the PPh(2) groups and a metallated Csp(3) atom. The Co(II) atom is centered in a trigonal-bipyramidal configuration.
Project description:In the title compound, [CoCl(2)(C(8)H(7)ClN)(C(3)H(9)P)(2)], the Co atom displays an octa-hedral coordination, with two cis Cl atoms perpendicular to two trans trimethyl-phosphine ligands as well as trans to the bidentate 3-chloro-2-methyl-imino-phenyl ligand.
Project description:In the title compound, C20H18N2P, the P atom is bonded to the two phenyl and imidazole groups, with an average P-C bond length of 1.828?(2)?Å. The three C-P-C bond angles have values consistent with a tetra-hedral geometry around the P atom with the fourth site occupied by a H atom. Crystal packing is through van der Waals inter-actions.
Project description:In the title ylide, C(31)H(28)ClO(2)P [common name ?-acetyl-?-p-chloro-benzoyl-methyl-enetri(p-tol-yl)phospho-rane], the dihedral angle between the 4-chloro-phenyl ring and that of the ylide moiety is 66.15?(10)°. The geometry around the P atom is slightly distorted tetra-hedral [angle range = 105.22?(8)-115.52?(9)°] and the carbonyl O atoms are syn-oriented with respect to the P atom. The ylide group is close to planar [maximum deviation from the least-squares plane = 0.006?(2)?Å] and the P-C, C-C and C=O bond lengths are consistent with electron delocalization involving the O atoms.
Project description:In the title compound, [RuCl(2)(C(6)H(6))(C(19)H(17)P)], the Ru(II) atom has a distorted pseudo-octa-hedral coordination environment with the metrical parameters around the metallic core as Ru-centroid(?(6)-benzene) = 1.6894?(11)?Å, Ru-P = 2.3466?(6), Ru-Cl(avg.) = 2.4127?(7)?Å; Cl-Ru-Cl = 88.07?(2) and Cl-Ru-P = 82.77?(2), 87.65?(2)°. The effective cone angle for the benzyl-diphenyl-phosphane was calculated to be 143°. In the crystal C-H?Cl and C-H?? inter-actions are observed.
Project description:The title compound, C15H18NO3PS·C6H6, is a rare example of a crystallographically characterized exocyclic phosphiniminium-arene-sulfonate zwitterion, which crystallises as its benzene solvate. The crystal structure shows that the N atom is protonated and that the iminium H atom forms both intra- and inter-molecular hydrogen bonds to the single-bonded sulfonate O atom in an R 2 (2)(4) graph-set motif. The dihedral angle between the aromatic rings in the main molecule is 89.49?(8)°.
Project description:In the structure of the title compound, [CoCl(2)(C(9)H(16)N(2)Si)(2)], the Co(II) atom is located on an inversion center in a slightly distorted tetra-hedral environment formed by two chloride ions and the pyridine N atoms of two chelating 6-methyl-2-[(trimethyl-silyl)amino]pyridine ligands. The dihedral angle between the planes of the pyridine rings is 80.06?(5)°. Cohesion within the crystal structure is accomplished by N-H?Cl hydrogen bonds.
