Crystal structure of di-chlorido-[2-(di-phenyl-phosphan-yl)-3,4,5,6-tetra-fluoro-benzene-1-thiol-ato-?(2) P,S]gold(III).

ABSTRACT: The title compound, [Au(C18H10F4PS)Cl2], crystallizes as neutral mol-ecules, with the Au(III) atom coordinated by two Cl atoms and by the P and S atoms of the bidentate phosphanyl thiol-ate ligand, in a slightly distorted square-planar environment. The mol-ecules are linked into centrosymmetric dimers via long axial Au-Cl bonds of 3.393?(4)?Å. This axial Au-Cl distance is longer than is usually seen, although one other example has been given. Dimer formation may explain the unexpectedly low solubility of the compound in common polar solvents. There is also a separate inter-molecular Au-F contact of 3.561?(6)?Å, but this distance seems too long to be regarded as a bond. Two putative C-H?F hydrogen bonds appear to link the dimers into sheets parallel to (110). There is a short inter-molecular F?F contact of 2.695?(10)?Å between two dimers related by the twofold axis.

Crystal structure of tetra-ethyl-ammonium chloride 3,4,5,6-tetra-fluoro-1,2-di-iodo-benzene.

Project description:Equimolar qu-anti-ties of tetra-ethyl-ammonium chloride (Et4NCl) and 3,4,5,6-tetra-fluoro-1,2-di-iodo-benzene (o-DITFB or o-C6F4I2) have been co-crystallized in a solution of di-chloro-methane yielding a pure halogen-bonded compound, 3,4,5,6-tetra-fluoro-1,2-di-iodo-benzene-tetra-ethyl ammonium chloride (2/1), Et4N(+)·Cl(-)·2C6F4I2, in the form of translucent needles. [(Et4NCl)(o-C6F4I2)2] packs in the C2/c space group. The asymmetric unit includes one mol-ecule of DITFB, one Et4N(+) cation located on a twofold rotation axis, and one chloride anion also located on a twofold rotation symmetry axis. This compound has an inter-esting halogen-bonding environment surrounding the halide. Here, the chloride anion acts as a tetra-dentate halogen bond acceptor and forms a distorted square-pyramidal geometry, with I?Cl(-)?I angles of 80.891?(6) and 78.811?(11)°, where two crystallographically distinct iodine atoms form halogen bonds with the chloride anion. Resulting from that square-pyramidal geometry are short contacts between some of the adjacent F atoms. Along the b axis, the halogen-bonding inter-action results in a polymeric network, producing a sheet in which the two closest chloride ions are 7.8931?(6)?Å apart. The Et4N(+) cation alternates in columns with the halide ion. The expected short contacts (shorter than the sum of their van der Waals radii) are observed for the halogen bonds [3.2191?(2) and 3.2968?(2)?Å], as well as almost linear angles [170.953?(6) and 173.529?(6)°].

Crystal structure of tetra-butyl-ammonium bromide-1,2-di-iodo-3,4,5,6-tetra-fluoro-benzene-di-chloro-methane (2/2/1).

Project description:The crystallization of a 1:1 molar solution of 1,2-di-iodo-3,4,5,6-tetra-fluoro-benzene (o-DITFB) and tetra-butyl-ammonium bromide (n-Bu4NBr) from di-chloro-methane yielded pure white crystals of a halogen-bonded compound, C16H36N(+)·Br(-)·C6F4I2·0.5CH2Cl2 or [(n-Bu4NBr)(o-DITFB)]·0.5CH2Cl2. The compound may be described as a quaternary system and may be classified as a salt-cocrystal solvate. The asymmetric unit contains one mol-ecule of solvent, two o-DITFB mol-ecules, two cations (n-Bu4N(+)) and two crystallographically distinct bromide ions [θI ⋯ Br- ⋯ I = 144.18 (1) and 135.35 (1)°]. The bromide ion is a bidentate halogen-bond acceptor which inter-acts with two covalently bonded iodines (i.e. halogen-bond donors), resulting in a one-dimensional polymeric zigzag chain network approximately along the a axis. The observed short contacts and angles are characteristic of the non-covalent inter-action [d C-I⋯Br = 3.1593 (4)-3.2590 (5) Å; θC-I⋯Br = 174.89 (7) and 178.16 (7)°]. It is noted that iodine acts as both a halogen-bond donor and a weak CH hydrogen-bond acceptor, while the bromide ions act as acceptors for weak CH hydrogen bonds and halogen bonds.

Poly[bis-(ethanol)(?4-2,3,5,6-tetra-fluoro-benzene-1,4-di-carboxyl-ato)cadmium].

Project description:In the title compound, [Cd(C8F4O4)(C2H5OH)2] n , the Cd(II) cation sits on an inversion centre and is coordinated by six O atoms from four tetra-fluoro-benzene-1,4-di-carboxyl-ate anions and two ethanol mol-ecules in a distorted octa-hedral geometry. The anionic ligand is also located on an inversion centre, and connects four Cd(II) cations, generating a two-dimensional polymeric layer parallel to the ab plane. Within the layer, the ethanol mol-ecule links F and O atoms of the nearest anionic ligands via O-H?O and O-H?F hydrogen bonds. The ethyl group of the ethanol mol-ecule is disordered over two positions with an occupancy ratio of 0.567?(10):0.433?(10).

trans-Chlorido-(4-fluoro-benzene-thiol-ato-κS)bis-(tri-phenyl-phosphane-κP)palladium(II) methanol hemisolvate.

Project description:The title compound, [Pd(SC6H4F-p)Cl(PPh3)2]·0.5CH3OH, features a Pd(II) complex with two tri-phenyl-phosphane (PPh3) ligands arranged in a trans conformation, with one chloride and one 4-fluoro-benzene-thiol-ate ligand completing the coordination sphere, giving rise to a slightly distorted square-planar geometry of the Pd(II) ion. The methanol solvent mol-ecule is disordered about an inversion centre with an occupancy of 0.25 for each molecule. In the crystal, weak C-H⋯Cl hydrogen-bonding inter-actions between the complex mol-ecules generate chain frameworks parallel to [010].

[2-(Diphenyl-phosphan-yl)benzene-thiol-ato-κP,S](pyridine-2-thiol-ato-κS)(triphenyl-phosphine-κP)palladium(II).

Project description:In the title compound, [Pd(C(5)H(4)NS)(C(18)H(14)PS)(C(18)H(15)P)], the Pd(II) atom has a slightly distorted square-planar environment. Two coordination sites are occupied by a P,S-chelating 2-(diphenyl-phosphan-yl)benzene-thiol-ate ligand and the other two by a P atom from a triphenyl-phosphine ligand and an S atom from a pyridine-2-thiol-ate ligand, exhibiting a trans arrangement of the two P-donor atoms. In the crystal structure, weak intra- and inter-molecular C-H⋯π and π-π inter-actions are observed. The pyridyl ring is equally disordered over two positions.

Project description:The crystal structure of the dinuclear arene ruthenium title complex, [Ru2(C6H5OS)(C7H7S)2(C10H14)2]BF4, shows the two Ru(II) atoms to be bridged by two benzyl-thio-pheno-late units and one 4-hy-droxy-thio-pheno-late unit, with the remaining three coordination sites of each Ru(II) atom being occupied by p-cymene ligands, completing the typical piano-stool coordination geometry. The BF4 (-) counter-anion is surrounded by four cationic dinuclear complexes, showing an O-H⋯F hydrogen bond and several weak C-H⋯F inter-actions. This is the first example of an X-ray analysis of a mixed dinuclear tri-thiol-ate arene ruthenium(II) complex.

trans-Bis(μ-benzene-thiol-ato-κ(2) S:S)bis[chlorido-(tri-phenyl-phosphane-κP)palladium(II)] chloro-form disolvate.

Project description:The title compound, [Pd2Cl2(C6H5S)2(C18H15P)2]·2CHCl3, contains a centrosymmetric dinuclear palladium complex with the Pd(II) cation in a slightly distorted square-planar coordination environment. The Pd(II) cations are bridged by the S atoms of two benzene-thiol-ate ligands with different Pd-S distances [2.2970 (11) and 2.3676 (11) Å]. The coordination of the metal atom is completed by a chloride anion [2.3383 (11) Å] and a tri-phenyl-phosphane ligand [2.2787 (11) Å]. Weak C-H⋯Cl inter-actions are present between complex mol-ecules and the CHCl3 solvent mol-ecule. The latter is disordered over two positions in a 0.792 (8):0.208 (8) ratio. The crystal under investigation was found to be twinned by nonmerohedry, with a fraction of 73.4 (1)% for the major twin component.

Project description:The asymmetric unit of the polymeric title compound, [Ni(C8H4O4)(C10H14N4)(H2O)] n , contains one Ni(2+) cation, one coordinating water mol-ecule, one 3,3',5,5'-tetra-methyl-4,4'-bi-pyrazole ligand and half each of two benzene-1,4-di-carboxyl-ate anions, the other halves being generated by inversion symmetry. The Ni(2+) cation exhibits an octa-hedral N2O4 coordination sphere defined by the O atoms of the water mol-ecule and two different anions and the N atoms of two symmetry-related N-heterocycles. The N-heterocycles and both anions bridge adjacent Ni(2+) cations into a three-dimensional network structure, with one of the anions in a bis-bidentate and the other in a bis-monodentate bridging mode. N-H⋯O and O-H⋯O hydrogen bonds between the N-heterocycles and water mol-ecules as donor groups and the carboxyl-ate O atoms as acceptor groups consolidate the crystal packing.

[5,10,15,20-Tetra-kis-(penta-fluoro-phen-yl)porphyrin-ato]zinc(II) benzene disolvate.

Project description:Single crystals of the title zinc porphyrinato complex, [Zn(C44H8F20N4)]·2C6H6, were obtained by the solvent evaporation method. The molecular complex exhibits point group symmetry with the central ZnII atom located on an inversion centre. The porphyrinato core is approximately planar, and the cation has no other ligating atoms than the four porphyrinato N atoms. π-π inter-actions between benzene solvent mol-ecules and [Zn(TFPP)] units lead to multilayer packing structures. In addition, inter-molecular C-H⋯F hydrogen bonding is observed between [Zn(TFPP)] mol-ecules.
