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(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

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
