Crystal structure of di-?-iodido-bis-[(dimethyl sulfoxide-?O)(tri-phenyl-phosphane-?P)copper(I)].

ABSTRACT: The centrosymmetric dinuclear title compound, [Cu2I2(C2H6OS)2(C18H15P)2], represents the first example of a CuI complex ligated by an O-bound dimethyl sulfoxide ligand. In the crystal, the two tetrahedrally coordinated Cu(I) atoms are bridged by two ?2-iodido ligands in an almost symmetrical rhomboid geometry. The loose Cu?Cu contact of 2.9874?(8)?Å is longer than the sum of the van der Waals radii of two Cu atoms (2.8?Å), excluding a significant cupriophilic inter-action in the actual dimer. C-H?O and C-H?I hydrogen bonding interactions as well as C-H??(aryl) interactions stabilize the three-dimensional supramolecular network.

The centrosymmetric dinuclear title compound, [Cu2I2(C2H6OS)2(C18H15P)2], represents the first example of a CuI complex ligated by an O-bound dimethyl sulfoxide ligand. In the crystal, the two tetrahedrally coordinated Cu(I) atoms are bridged by two μ2-iodido ligands in an almost symmetrical rhomboid geometry. The loose Cu⋯Cu contact of 2.9874 (8) Å is longer than the sum of the van der Waals radii of two Cu atoms (2.8 Å), excluding a significant cupriophilic inter-action in the actual dimer. C- ...[more]

Crystal structure of [N,N-bis-(di-phenyl-phospho-ro-thio-yl)amidato-?2S,S']bis-(tri-phenyl-phosphane-?P)copper(I) di-chloro-methane monosolvate.

Project description:The title compound, [Cu(C24H20NP2S2)(C18H15P)2]·CH2Cl2 or [Cu(dppaS2)(PPh3)2]·CH2Cl2, is a neutral mononuclear copper(I) complex bearing an N,N-bis-(di-phenyl-phospho-rothio-yl)amidate (dppaS2-) ligand and two tri-phenyl-phosphane ligands. The molecular structure shows that the two S atoms of the dppaS2- ligand [Cu-S = 2.3462?(9) and 2.3484?(9)?Å] and the two P atoms of the two tri-phenyl-phosphane ligands [Cu-P = 2.3167?(9) and 2.2969?(9)?Å] coordinate to the copper(I) atom, resulting in a tetra-hedral coordination geometry. The crystallographically observed mol-ecular structure is compared to the results of DFT calculations.

Bis(?-di-phenyl-phosphan-yl)bis-[(tri-methyl-phosphane)cobalt(I)](Co-Co).

Project description:The title compound, [Co2{P(C6H5)2}2(C3H9P)4], was obtained by the addition of di-phenyl-phosphane to a solution of Co(CH3)(C3H9P)4. The dinuclear complex mol-ecule exhibits inversion symmetry with the inversion centre located between the two Co(I) atoms. The short Co-Co distance of 2.3670?(8)?Å lies within the range of metal-metal double bonds. As a result of inversion symmetry, the four-membered Co2P2 core is rigorously planar, and the two bridging P(C6H5)2-ligands and the terminal C3H9P ligands are arranged in a pseudo-tetra-hedral fashion about the Co(I) atom.

Crystal structure of di-?-iodido-bis-[bis(aceto-nitrile-?N)copper(I)].

Project description:The title compound, [Cu2I2(CH3CN)4], exhibits a centrosymmetric Cu2I2 core [Cu?Cu distance = 2.7482?(11)?Å], the Cu(I) atoms of which are further coordinated by four mol-ecules of aceto-nitrile. The Cu(I) atom has an overall distorted tetra-hedral coordination environment evidenced by L-Cu-L angles (L = N or I) ranging from 100.47?(10) to 117.06?(2)°. The coordination geometries of the aceto-nitrile ligands deviate slightly from linearity as shown by Cu-N-C angles of 167.0?(2) and 172.7?(2)°. In the crystal, there are no significant hydrogen-bonding inter-actions present, so the crystal packing seems to be formed predominantly by van der Waals forces.

Bis(tetra-phenyl-phospho-nium) di-μ-iodido-bis[di-iodido-tellurate(II)].

Project description:The structure of the title compound, (C(24)H(20)P)(2)[Te(2)I(6)], is composed of discrete PPh(4) (+) cations and centrosymmetric [Te(2)I(6)](2-) anions. The tellurium(II) atom shows a sligthly distorted square-planar TeI(4) geometry and is coordinated to two bridging and two terminal iodine atoms. The planar [Te(2)I(6)](2-) ions are isolated by the cations and no inter-molecular tellurium-halogen or halogen-halogen inter-actions are present.

catena-Poly[[(triphenyl-phosphane)copper(I)]-di-?-iodido-[(triphenyl-phosphane)copper(I)]-?-{1,2-bis-[1-(pyridin-4-yl)ethyl-idene]hydrazine}].

Project description:In the title coordination polymer, [Cu(2)I(2)(C(14)H(14)N(4))(C(18)H(15)P)(2)](n), the Cu(I) atom is coordinated by two I atoms, one P atom and one N atom in a fairly regular tetra-hedral arrangement. A crystallographic inversion centre generates a Cu(2)I(2) diamond with a Cu-Cu separation of 3.0120?(5)?Å. The complete N,N'-(1-pyridin-4-yl-ethethyl-idene)-hydrazine mol-ecule is also generated by inversion symmetry, and this bridging ligand leads to [011] polymeric chains in the crystal structure.

Crystal structure of (μ-1,4-di-carb-oxy-butane-1,4-di-carboxyl-ato)bis-[bis-(tri-phenyl-phosphane)silver(I)] di-chloro-methane tris-olvate.

Project description:The mol-ecular structure of the tetra-kis(tri-phenyl-phosphan-yl)disilver salt of butane-1,1,4,4-tetra-carb-oxy-lic acid, [Ag2(C8H8O8)(C18H15P)4]·3CH2Cl2, crystallizes with one and a half mol-ecules of di-chloro-methane in the asymmetric unit. The coordination complex exhibits an inversion centre through the central CH2-CH2 bond. The Ag(I) atom has a distorted trigonal-planar P2O coordination environment. The packing is characterized by inter-molecular T-shaped π-π inter-actions between the phenyl rings of the PPh3 substituents in neighbouring mol-ecules, forming a ladder-type superstructure parallel to [010]. These ladders are arranged in layers parallel to (101). Intra-molecular hydrogen bonds between the OH group and one O atom of the Ag-bonded carboxyl-ate group results in an asymmetric bidendate coordination of the carboxyl-ate moiety to the Ag(I) ion.

Bis(dimethyl sulfoxide)-hydridobis(triphenyl-phosphane)cobalt(I).

Project description:The title compound, [CoH(C(18)H(15)P)(2)(C(2)H(6)OS)(2)], was synthesized by the reaction of chloridotris(triphenyl-phosphane)cobalt(I), [ClCo(PPh(3))(3)], in the presence of one equivalent potassium hydridotris(pyrazol-yl)borate in dimethyl sulfoxide. The structure displays a distorted trigonal-pyramidally coordinated cobalt(I) atom, with two phosphane ligands and one DMSO ligand in the equatorial plane. The coordination is completed by one further DMSO ligand and the anionic hydride in the axial positions.

Crystal structure of ?-oxalato-?2O1:O2-bis-[(dimethyl sulfoxide-?O)tri-phenyl-tin(IV)].

Project description:In the previously reported [C2O4(SnPh3)2] complex [Diop et al. (2003 ?). Appl. Organomet. Chem.17, 881-882.], the SnIV atoms are able to formally complete their coordination by addition of dimethyl sulfoxide (DMSO) mol-ecules provided by the reaction medium, affording the title complex, [Sn2(C6H5)6(C2O4)(C2H6OS)2]. The SnIV atoms are then penta-coordinated, with a common trans trigonal-bipyramidal arrangement. The asymmetric unit contains one half-mol-ecule, which is completed by inversion symmetry in space group type C2/c. The inversion centre is placed at the mid-point of the central bis-monodentate oxalate dianion, C2O42-, which bridges the [(SnPh3)(DMSO)] moieties. The mol-ecule crystallizes as a disordered system, with two phenyl rings disordered by rotation about their Sn-C bonds, while the DMSO mol-ecule is split over two positions due to a tetra-hedral inversion at the S atom. All disordered parts were refined with occupancies fixed of 0.5.

Crystal structure of bromido-nitro-syl-bis(tri-phenyl-phosphane-κP)nickel(II).

Project description:The asymmetric unit of the title complex, [NiBr(NO){P(C6H5)3}2], comprises two independent mol-ecules each with a similar configuration. The Ni(II) cation is coordinated by one bromide anion, one nitrosyl anion and two tri-phenyl-phosphane mol-ecules in a distorted BrNP2 tetra-hedral coordination geometry. The coordination of the nitrosyl group is non-linear, the Ni-N-O angles being 150.2 (5) and 151.2 (5)° in the two independent mol-ecules. In the crystal, mol-ecules are linked by weak C-H⋯Br hydrogen bonds and weak C-H⋯π inter-actions into a three-dimensional supra-molecular architecture.

Bis[2,6-bis-(3,5-dimethyl-1H-pyrazol-1-yl)pyridine]di-?(3)-iodido-diiodidotetra-copper(I).

Project description:In the title centrosymmetric tetra-nuclear complex, [Cu(4)I(4)(C(15)H(17)N(5))(2)], the two distinct Cu(I) atoms adopt similar tetra-hedral arrangements, each being ligated by two I atoms, and two N atoms from one 2,6-bis-(3,5-dimethyl-1H-pyrazol-1-yl)pyridine ligand. In the crystal, there are no hydrogen bonds present, and only very weak ?-? inter-actions are observed [centroid-centroid distance = 3.985?(4)?Å], which connect neighbouring tetra-nuclear units into a chain motif along the b axis.
