Crystal structure of fac-tricarbon-yl(quinoline-2-carboxyl-ato-κ(2) N,O)(tri-phenyl-arsane-κAs)rhenium(I).

ABSTRACT: In the title compound, [Re(C10H6NO2)(CO)3{As(C6H5)3}], the coordination environment of Re(I) is that of a distorted octa-hedron. Three coordination sites are occupied by three carbonyl groups in a facial arrangement and the remaining three sites by tri-phenyl-arsane and deprotonated quinaldic acid in As-mono- and N,O-bidentate fashions, respectively. In the crystal, the complexes are linked through weak C-H⋯O hydrogen bonds, forming a three-dimensional network. It worth noting that, as far as we know, this complex is the first Re(I) tri-phenyl-arsane tricarbonyl compound to be reported.

Crystal structure of fac-tricarbon-yl(cyclo-hexyl isocyanide-κC)(quinoline-2-carboxyl-ato-κ(2) N,O)rhenium(I).

Project description:In the title compound, [Re(C10H6NO2)(C7H11N)(CO)3], the Re(I) atom is coordinated by three carbonyl ligands in a facial arrangement and by the N, O and C atoms from a chelating quinaldate anion and a monodentate isocyanide ligand, respectively. The resultant C4NO coordination sphere is distorted octa-hedral. A lengthening of the axial Re-CO bond trans to the isocyanide ligand is indicative of the trans effect. Individual complexes are stacked into rods parallel to [001] through displaced π-π inter-actions. Weak C-H⋯O hydrogen-bonding inter-actions between the rods lead to the formation of layers parallel to (010). These layers are stacked along [010] by C-H⋯H-C van der Waals contacts.

Aqua-tricarbon-yl(4-carboxy-pyridine-2-carboxyl-ato-?N,O)rhenium(I).

Project description:There are two mol-ecules with similar bond dimensions in the asymmetric unit of the title complex, [Re(C(7)H(4)NO(4))(CO)(3)(H(2)O)]. The metal centre is coordinated facially by three carbonyl groups, is chelated by a 4-carboxy-pyridine-2-carboxyl-ate ligand and is also coordinated by a water mol-ecule. O-H?O hydrogen bonds give rise to a three-dimensional network.

Crystal structure of fac-aquatricarbonyl[(S)-valin-ato-κ(2) N,O]-rhenium(I).

Project description:In the mol-ecule of the title compound, [Re(C5H10NO2)(CO)3(H2O)], the Re(I) atom adopts a distorted octa-hedral coordination sphere defined by one aqua and three carbonyl ligands as well as one amino N and one carboxyl-ate O atom of the chelating valinate anion. The carbonyl ligands are arranged in a fac-configuration around the Re(I) ion. In the crystal, an intricate hydrogen-bonding system under participation of two O-H, two N-H and one C-H donor groups and the carboxyl-ate and carbonyl O atoms as acceptor groups contribute to the formation of a three-dimensional supra-molecular network.

fac-Aceto-nitrile-tricarbon-yl(di-methyl-carbamodi-thio-ato-κ2S,S')rhenium(I): crystal structure and Hirshfeld surface analysis.

Project description:The title compound, [Re(C3H6NS2)(C2H3N)(CO)3], features an octa-hedrally coordinated ReI atom within a C3NS2 donor set defined by three carbonyl ligands in a facial arrangement, an aceto-nitrile N atom and two S atoms derived from a symmetrically coordinating di-thio-carbamate ligand. In the crystal, di-thio-carbamate-methyl-H⋯O(carbon-yl) inter-actions lead to supra-molecular chains along [36-1]; both di-thio-carbamate S atoms participate in intra-molecular methyl-H⋯S inter-actions. Further but weaker aceto-nitrile-C-H⋯O(carbonyl) inter-actions assemble mol-ecules in the ab plane. The nature of the supra-molecular assembly was also probed by a Hirshfeld surface analysis. Despite their weak nature, the C-H⋯O contacts are predominant on the Hirshfeld surface and, indeed, on those of related [Re(CO)3(C3H6NS2)L] structures.

fac-Tricarbon-yl(pyridine-?N)(1,1,1-trifluoro-acetyl-acetonato-?O,O')rhenium(I).

Project description:In the title compound, [Re(C(5)H(4)F(3)O(2))(C(5)H(5)N)(CO)(3)], the Re(I) atom is six-coordinated owing to bonding by three carbonyl ligands arranged in a fac configuration, two O atoms from the bidentate 1,1,1-trifluoro-acetyl-acetonate ligand and an N atom from a pyridine ligand. In the crystal, the mol-ecules pack in layers, diagonally, in a head-to-tail fashion across the ab plane. These layers are stabilsed by inter-molecular C-H?O and C-H?F hydrogen bonds.

Bis(?-2-phenyl-quinoline-4-carboxyl-ato)-?O,O':O;?O:O,O'-bis-[(2,2'-bipyridine-?N,N')(2-phenyl-quinoline-4-carboxyl-ato-?O,O')cadmium(II)].

Project description:The neutral binuclear title complex, [Cd(2)(C(16)H(10)NO(2))(4)(C(10)H(8)N(2))(2)], is centrosymmetric, with the inversion center generating the central (?-O)(2)Cd(2) bridge. The Cd(II) ion is in a strongly distorted CdN(2)O(5) penta-gonal-bipyramidal geometry, defined by two N atoms from one 2,2'-bipyridine ligand and five O atoms from three 2-phenyl-quinoline-4-carboxyl-ate ligands, one monodentate, two bidentate. Weak inter-molecular ?-? inter-actions [centroid-centroid distance = 3.712?(3)?Å] help to establish the packing of the structure.

Bis(?-2-phenyl-quinoline-4-carboxyl-ato)bis-[aqua-(1,10-phenanthroline)(2-phenyl-quinoline-4-carboxyl-ato)manganese(II)] dihydrate.

Project description:In the centrosymmetric dinuclear title complex, [Mn(2)(C(16)H(10)NO(2))(4)(C(12)H(8)N(2))(2)(H(2)O)(2)]·2H(2)O, the Mn(II) cation is in a distorted octa-hedral coordination geometry defined by two N atoms from a 1,10-phenanthroline ligand, one water O atom and three O atoms from three 2-phenyl-quinoline-4-carboxyl-ate anions. A pair of 2-phenyl-quinoline-4-carboxyl-ate anions bridge two Mn cations, forming the dinuclear mol-ecule. An intra-moleculr O-H?O hydrogen bond occurs. Inter-molecular O-H?O and O-H?N hydrogen bonds are present in the crystal structure.

Crystal structure of bromido-fac-tricarbon-yl[5-phenyl-3-(pyridin-2-yl)-1H-1,2,4-triazole-?(2) N,N']rhenium(I).

Project description:In the title compound, [ReBr(C13H10N4)(CO)3], the Re(I) atom has a distorted octa-hedral coordination environment. Two N atoms of the 5-phenyl-3-(pyridin-2-yl)-1H-1,2,4-triazole ligand and two of the three carbonyl groups occupy the equatorial plane of the complex, with the third carbonyl ligand and the bromide ligand in the axial positions. The three carbonyl ligands are arranged in a fac configuration around the Re(I) atom. Mutual N-H?Br hydrogen bonds arrange mol-ecules into centrosymmetric dimers. Additional stabilization within the crystal structure is provided by C-H?O and C-H?Br hydrogen bonds, as well as by slipped ?-? stacking inter-actions [centroid-to-centroid distance = 3.785?(5)?Å], defining a three-dimensional network.

Poly[bis-(?-hemihydrogen 2-phenyl-quinoline-4-carboxyl-ato-?N,O)silver(I)].

Project description:In the title compound, [Ag(C(16)H(10.5)NO(2))(2)], the Ag(I) cation (site symmetry 2) is coordinated by two N atoms in a near-linear AgN(2) arrangement. Two carboxyl-ate O atoms from two additional 2-phenyl-quinoline-4-carboxyl-ate ligands form long Ag-O bonds [2.6585?(17)?Å], resulting in a distorted square-planar arrangement. The bridging ligands result in infinite corrugated sheets propagating in (010). An O-H?O hydrogen bond, disordered about a twofold axis, completes the structure.

fac-Bromidotricarbonyl[2-(diisopropylphosphanyl)benzaldehyde-κ(2)O,P]rhenium(I).

Project description:The structure of the title complex, [ReBr(C(13)H(19)OP)(CO)(3)], displays a facial coordination of the three CO ligands and a κ(2)O,P coordination mode of the 2-diisopropyl-phosphino-benzaldehyde ligands. The Re-C bond distance for the CO ligand trans to the P atom is, due to its trans influence, elongated to 1.943 (3) Å, showing that this CO ligand is more weakly bound to the Re centre than the other two.
