Rac-cis-Dicarbonyl-chlorido{1-[2-(diphenyl-phosphanyl-?P)benz-yl]-3-(phenyl-?C(1))imidazol-2-yl-idene-?C(2)}ruthenium(II) dichloro-methane monosolvate.

ABSTRACT: In the title compound, [Ru(C(28)H(22)N(2)P)Cl(CO)(2)]·CH(2)Cl(2), the Ru(II) atom exhibits a distorted octa-hedral coordination geometry. The N-phenyl group of the ligand has undergone orthometalation; as a result, the tridentate phosphane-functionalized N-heterocyclic carbene ligand is coordinating in a meridional fashion. This complex is of inter-est with respect to transfer hydrogenation catalysis and also provides an example of C-H activation behavior in late transition metal complexes. The dichloro-methane solvent mol-ecule is disordered over two sets of sites with an occupancy ratio of 0.873?(14):0.127?(14).

{2-[(Benzylphenyl-phosphanyl-κP)methyl]phenyl-κC}iodidobis(trimethyl-phos-phane)cobalt(II).

Project description: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.

Synthesis and crystal structure of trans-di-chlorido[3-methyl-1-(4-vinyl-benz-yl)-1H-imidazol-3-ium-2-yl-κC (2)](4-phenyl-pyridine-κN)palladium(II).

Project description:The title compound, [PdCl2(C11H9N)(C13H14N2)], represents a new class of palladium-based polymerizable monomer which could give a potentially catalytically active polymer. It was synthesized via transmetallation from the corresponding silver complex. The Pd(II) ion coordinates two Cl anions, one C atom from the N-heterocyclic carbene (NHC) ligand and one N atom from the 4-phenyl-pyridine ligand, displaying a slightly distorted square-planar geometry. The dihedral angle between the imidazole ring and the pyridine ring is 34.53 (8)°. The Pd-C bond length between the NHC ligand and the Pd(II) ion is 1.9532 (16) Å. In the crystal, weak non-classical C-H⋯Cl hydrogen bonds link the mol-ecules into a tape structure along [101]. A weak π-π inter-action is also observed [centroid-centroid distance = 3.9117 (11) Å].

(+)-Chlorido[(1,2,3,4-?;?P)-2'-diphenyl-phosphanyl-2-diphenyl-phosphoryl-1,1'-binaphth-yl]rhodium(I) methanol monosolvate.

Project description:In the title complex, [RhCl(C(44)H(32)OP(2))]·CH(3)OH, the Rh(I) ion is coordinated by a naphthyl group of a partially oxidized 2,2'-bis-(diphenyl-phosphan-yl)-1,1'-binaphthyl (BINAP) ligand in a ?(4) mode, one P atom of the diphenyl-phosphanyl group and one Cl atom. The P=O group does not inter-act with the Rh(I) ion but accepts an O-H?O hydrogen bond from the methanol solvent mol-ecule.

Chlorido(2-imino-methyl-3-fluoro-phenyl-κC,N)tris-(trimethyl-phos-phane-κP)iron.

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.

Tetra-bromido-[4-(triphenyl-phosphanyl-oxy)but-yl]tellurium acetonitrile monosolvate.

Project description:In the title compound, [TeBr(4)(C(22)H(23)OP)]·CH(3)CN, the Te atom exhibits a square-pyramidal coordination with an apical Te-C bond and four basal Te-Br bonds. The conformation of the aliphatic C-C-C-C chain is gauche [torsion angle = -67.7?(8)°]. A weak C-H?Br inter-action helps to establish the conformation. In the crystal, there is a weak secondary bonding inter-action [Te?N = 3.456?(11)?Å] between the Te atom and the N atom of the solvent mol-ecule, which completes a distorted TeNCBr(4) octa-hedron. Inversion dimers linked by pairs of C-H?Br inter-actions are also observed.

Di-μ-chlorido-bis-{[2-(morpholinometh-yl)phenyl-κC,N]palladium(II)}.

Project description:The title compound, [Pd(2)(C(11)H(14)NO)(2)Cl(2)], has a dimeric structure with Cl atoms bridging the two Pd atoms, one half of the mol-ecule being generated by symmetry due to the crystallographic inversion centre located in the middle of the perfectly planar Pd(2)Cl(2) ring. The five-membered ring adopts an envelope conformation, while the morpholino group has a chair conformation. The geometry around the metal centres is distorted square-planar, as a result of a strong intra-molecular N→Pd coordination trans to a Pd-Cl bond. In the crystal structure, the dimeric structure is strengthened by inter-molecular C-H⋯Cl hydrogen bonds. C-H⋯C(phen-yl) inter-actions link the dimers into a columnar supra-molecular array along the a axis; the dimers are further connected by C-H⋯Ph inter-actions into a three-dimensional supra-molecular arrangement.

Project description:The title compound, [PtCl(2)(C(25)H(21)N(2)P)], is a Pt(II) complex with an NPCl(2) coordination sphere in which the metal is coordinated to the imino N and phosphane P atoms of the ligand and to two chloride ions.

Project description:The title compound, [Ru(C(10)H(15))Cl(C(12)H(10)ClP)(C(17)H(20)NP)], is a half-sandwich complex of Ru(II) with the chloro-diphenyl-phosphine ligand formed from the diphenyl-piperidinophosphine and chlorine of the precursor complex [Ru(η(5)-C(5)Me(5))(κ(1)P-Ph(2)PNC(5)H(10))Cl(2)] by an unexpected reaction with NaBH(4). The complex has a three-legged piano-stool geometry, with Ru-P bond lengths of 2.2598 (5) Å for the chloro-phosphine and 2.3303 (5) Å for the amino-phosphine.

Monoclinic polymorph of 4-[(1H-benz-imidazol-1-yl)meth-yl]benzoic acid.

Project description:Three polymorphs of the title compound, C(15)H(12)N(2)O(2), were obtained accidentally as single crystals in the hydro-thermal reaction of the title compound with manganese bromide in the presence of N,N'-dimethyl-formamide at 373?K. Here we report the structure of the first polymorph. The benzimidazole ring is almost planar, the maximum deviation from the mean plane being 0.016?(1)?Å. The benzimidazole and benzene rings are approximately perpendicular, making a dihedral angle 85.56?(7)°, which is a reflection of the axial rotation of the flexible benzimidazolyl arm. In the crystal, adjacent mol-ecules are connected through O-H?N hydrogen bonds into a chain along [100], and neighboring chains are further linked by via weak C-H?O hydrogen-bonding inter-actions, forming a two-dimensional network.
