catena-Poly[copper(I)-bis(μ-trifluoromethanesulfonato-κ2 O:O′)-copper(I)-bis(μ-trimethyl trithiophosphite)-κ2 P:S;κ2 S:P]
The title compound, [Cu2(CF3SO3)2(C3H9PS3)2]n, crystallizes as infinite chains in which two trimethyl trithiophosphite ligands and two trifluoromethanesulfonate anions bridge the essentially tetrahedrally coordinated CuI ions in an alternating fashion. The P and one S atom of each trimethyl trithiophosphite ligand are employed for coordination. The molecular structure exhibits the rare motif of copper(I) bridged by two trifluoromethanesulfonate anions generating eight-membered rings
Bis(1,1,2,2-tetramethyldiphosphane-1,2-dithione-κ2 S,S′)gold(I) trifluoromethanesulfonate
In the title compound, [Au(C4H12P2S2)2](CF3SO3), the gold(I) atom is tightly bonded to two S atoms belonging to different ligand molecules and forms two weaker contacts to the remaining S atoms. The coordination geometry around gold is intermediate between linear-dicoordinate and tetrahedral with an S—Au—S angle of 161.49 (3)°
[Bis(4-methyl-1,3-thiazol-2-yl-κN)methane]tricarbonyldichloridotungsten(II)
The title compound, [WCl2(C9H10N2S2)(CO)3], is a heptacoordinate tungsten(II) complex with a capped–octahedral coordination sphere in which one CO ligand caps a face formed by a chloro ligand and the two other carbonyls. The chloro ligands are mutually trans positioned at an angle of 156.98 (7)°. The chelating bis(4-methyl-1,3-thiazol-2-yl)methane ligand coordinates with the imine N atoms. In the crystal, molecules are linked into chains parallel to [201] by weak C—H⋯O contacts between the CH2 group of the bis(4-methylthiazol-2-yl)methane ligand and the O atom of the capping CO group
(m-Phenylenedimethylene)bis(triphenylphosphonium) bis[chlorido(pentafluorophenyl)aurate(I)] dichloromethane disolvate
The title compound, (C44H38P2)[AuCl(C6F5)]2·2CH2Cl2, crystallizes with a twofold rotation axis through the central benzene ring in the bis-phosphonium dication. In the crystal, the dications and anions are ordered into columns running parallel to the c axis by contacts of the pro-ylidic CH2 groups with the Cl atom of one and an ortho-F atom of another anion. The space between the columns is occupied by CH2Cl2 solvent molecules
[(3-Methylphenyl)(triphenylphosphonio)methanide-κC]triphenylphosphorane}(pentafluorophenyl-κC)gold(I) diethyl ether solvate
The metal atom in the title ylid–gold(I) adduct, [Au(C6F5)(C26H23P)]·C4H10O, exists in a linear coordination environment [C—Au—C = 174.1 (2)°]. The molecule has a short intramolecular contact involving an aromatic H atom (Au⋯H = 2.64 Å); two adjacent molecules are linked by an Au⋯Hylid interaction (Au⋯H = 3.14 Å)
Bis[μ-1,2-bis(diphenylphosphino)ethane-κ2 P:P′]digold(I)(Au—Au) bis(trifluoromethanesulfonate) acetonitrile disolvate
The title compound, [Au2(C26H24P2)2](CF3SO3)2·2CH3CN, comprises a cyclic cation with a short intramolecular aurophilic interaction of 2.9220 (3) Å. The trifluoromethanesulfonate anions and acetonitrile solvent molecules are located in channels formed by the complex cations that run along the crystallographic c axis. Each counter-anion is also engaged in a C—H⋯O contact with one of the methylene H atoms of a 1,2-bis(diphenylphosphino)ethane (dppe) ligand; another C—H⋯O contact involving an aromatic H atom is also observed
1,1,2,2-Tetrakis(1,3-benzoxazol-2-yl)ethene
The title compound, C30H16N4O4, reveals crystallographic and molecular symmetry and accordingly the asymmetric unit comprises one half-molecule. The dihedral angle between the planes of the two geminal benzoxazole rings is 74.39 (5)°. The packing features weak C—H⋯N and π–π interactions [centroid–centroid distance = 3.652 (1) Å]
1,3-Dimesitylimidazolidinium tetrachloridogold(III) dichloromethane solvate
The title ionic compound, (C21H27N2)[AuCl4]·CH2Cl2, was obtained from the reaction of 1,3-dimesitylimidazolidinium chloride with t-BuOK and a solution of AuCl3 in tetrahydrofuran. In the crystal structure, numerous weak C—H⋯Cl hydrogen bonds form double layers parallel to (100), which are further stabilized by π–π interactions between mesitylene rings [centroid–centroid distance = 4.308 (4) Å], resulting in the formation of a three-dimensional supramolecular assembly
2,2′-(Sulfanediyldimethylene)bis(1,3-benzothiazole)
In the title compound, C16H12N2S3, the two benzothiazole groups are oriented differently with respect to the –CH2– groups, one being approximately staggered and one nearly eclipsed. A sulfur–π interaction of 3.3627 (11) Å is observed between the bridging thioether S atom and a thiazole ring. The crystal packing is further stabilized by intermolecular C—H⋯N and C—H⋯π interactions
Pentacarbonyl-2κ5 C-chlorido-1κCl-bis[1(η5)-cyclopentadienyl](μ-α-oxidobenzylidene-1:2κ2 O:C)titanium(IV)tungsten(0)
The title compound, [TiW(C5H5)2(C7H5O)Cl(CO)5], consists of two metal centres, with a (tungstenpentacarbonyl)oxyphenylcarbene unit coordinated by a titanocene chloride. The oxycarbene group is nearly planar, with the phenyl ring twisted by an angle of 39.1 (2)° with respect to this plane. One of the cyclopentadienyl rings undergoes an offset face-to-face π–π interaction [3.544 (6) Å] with the symmetry-related cyclopentadienyl ring of a neighbouring molecule
