Poly[bis-[μ-1,3-bis-(diphenyl-phosphan-yl)propane-κP:P']-di-μ-thio-cyanato-κS:N;κN:S-disilver(I)].

ABSTRACT: In the title coordination polymer, [Ag(2)(NCS)(2)(C(27)H(26)P(2))(2)](n), two centrosymmetrically related Ag(+) cations are linked by two thio-cyanate anions into binuclear eight-membered macrocycles. The Ag⋯Ag separation within the macrocycle is 5.4400 (6) Å. The distorted tetra-hedral coordination about each metal atom is completed by the P atoms of two bridging 1,3-bis-(diphenyl-phosphan-yl)propane ligands, forming polymeric ribbons parallel to the a axis.

catena-Poly[silver(I)-bis-[μ-bis-(diphenyl-phosphino)methane-κP:P']-μ-thio-cyanato-κS:S-silver(I)-μ-thio-cyanato-κS:N].

Project description:The title compound, [Ag(NCS)(C(25)H(22)P(2))](n), contains two Ag(+) ions, two thio-cyanate ions and two bis-(diphenyl-phosphino)methane (dppm) ligands in the asymmetric unit. One of the thiocyanate ions bridges the two Ag(+) ions in a μ(2)-mode from its S atom and the two dppm ligands bridge the silver ions in a μ(1),μ(1) mode. The remaining SCN(-) ion bridges the binuclear units via its N and S atoms, generating a one-dimensional polymer propagating in [01]: the resulting AgP(2)SN and AgP(2)S(2) coordination geometries could be described as distorted tetra-hedral.

[μ-Bis(diphenyl-phosphan-yl)acetonitrile-κP:P]bis-[chloridogold(I)].

Project description:The title complex, [Au(2)Cl(2)(C(26)H(21)NP(2))], has an intra-molecular Au⋯Au inter-action of 3.1669 (4) Å, but no inter-molecular Au⋯Au inter-actions in the solid state. The Cl-Au-P bond angle of 176.84 (7)° is slightly distorted from linearity. The P-C bond length to the phenyl group is shorter [1.810 (7) Å] than the P-C bond length [1.876 (7) Å] to the bridging carbon, indicative of the flexibility of the bidentate bite of the ligand. The C-C N fragment is essentially linear at 179.5 (9)° and the C N bond length of 1.125 (11) Å indicates predominantly triple-bond character. In the crystal packing, there are no hydrogen-bonding or aurophilic inter-actions between the mol-ecules.

Poly[[μ(3)-chlorido-bis(μ(2)-thio-urea-κS)disilver(I)] nitrate].

Project description:The mol-ecular structure of the title polymeric complex, {[Ag(2)Cl(CH(4)N(2)S)(2)]NO(3)}(n), consists of a binuclear cationic complex and a nitrate counter-ion. The cationic complex contains two bridging thio-urea (Tu) ligands and a triply bridging μ(3)-Cl anion. The latter is probably released from 2-amino-ethane-thiol hydro-chloride during the synthesis. The coordination environment around the two Ag(I) atoms is different; one is trigonal planar, being coordinated by two thio-urea ligands through the S atoms and to one Cl(-) ion, while in the other the Ag(I) atom is tetra-hedrally coordinated by two thio-urea ligands through the S atoms and to two Cl(-) ions. These units aggregate through the Cl(-) anion and the Tu S atoms, forming a chain propagating in [100]. In the crystal structure, the polymeric chains are linked via N-H⋯O and N-H⋯Cl hydrogen bonds, forming a double layer two-dimensional network propagating in (011).

[μ-1,2-Bis(diphenyl-phosphan-yl)benzene-κP:P']bis-[chloridogold(I)].

Project description:In the crystal structure of the non-solvate form of the title compound, [Au(2)Cl(2)(C(30)H(24)P(2))], two almost linear P-Au(I)-Cl units [175.87 (3) and 171.48 (3)°] are in a skewed arrangement with a Cl-Au⋯Au-Cl torsion angle of -65.29 (3)° so as to form an intra-molecular Au⋯Au inter-action [3.0563 (2) Å]. The complex mol-ecules are connected each other through inter-molecular C-H⋯π inter-actions, giving a sheet structure parallel to the bc plane.

[μ-1,3-Bis(diphenyl-phosphino)propane-κP:P']bis-[bromidogold(I)].

Project description:The title compound, [Au(2)Br(2)(C(27)H(26)P(2))], features linearly coordinated Au(I) atoms within P,Br-donor sets. The central portion of the mol-ecule is practically planar as quanti-fied by the Br-Au⋯Au-Br torsion angle of -169.9 (2)°. The P-Au-Br chromophores are twisted with respect to each other [dihedral angle = 52.3 (6)°]. The benzene rings on each P atom lie on either side of this plane. The Au atoms are positioned at the periphery of the mol-ecule, which facilitates the formation of Au⋯Au inter-actions [3.2575 (11) Å] that result in the formation of supra-molecular chains along the b-axis direction. The Au⋯Au inter-actions are responsible for the deviations from the ideal linear geometry for each Au atom.

Di-μ-thio-cyanato-κN:S;κS:N-bis-[bis-(2-methyl-1H-benzimidazole-κN)(thio-cyanato-κN)cadmium(II)].

Project description:The title compound, [Cd(2)(NCS)(4)(C(8)H(8)N(2))(4)], is a centrosymmetric dinuclear cadmium(II) complex in which each two metal ions are linked by a pair of thio-cyanate N:S-bridges. Two 2-methyl-benzimidazole N-atom donors and one terminal thio-cyanate N atom complete a highly distorted square-pyramidal geometry around the Cd atom. In the crystal structure, two N-H⋯S hydrogen-bonding inter-actions occur, resulting in a three-dimensional polymeric structure. The apical 2-methyl-benzimidazole ring and its symmetry-related counterpart are arranged in an anti-parallel manner with a centroid-centroid separation of 3.6050 (14) Å, indicative of a π-π inter-action.

Crystal structure of bis-(thio-cyanato-κS)bis-(thio-urea-κS)mercury(II).

Project description:In the title complex, [Hg(NCS)2(CH4N2S)2], the Hg(II) atom is four-coordinated having an irregular four-coordinate geometry composed of four thione S atoms of two thio-cyanate groups and two thio-urea groups. The S-Hg-S angles are 172.02 (9)° for the trans-thio-cyanate S atoms and 90.14 (5)° for the cis-thio-urea S atoms. The mol-ecular structure is stabilized by an intra-molecular N-H⋯S hydrogen bond, which forms an S(6) ring motif. In the crystal, mol-ecules are linked by a number of N-H⋯N and N-H⋯S hydrogen bonds, forming a three-dimensional framework. The first report of the crystal structure of this compound appeared in 1966 [Korczynski (1966 ▶). Rocz. Chem. 40, 547-569] with an extremely high R factor of 17.2%, and no mention of how the data were collected.

Crystal structure of [1,3-bis-(di-phenyl-phosphan-yl)propane-κ(2) P,P'](N,N'-di-methyl-thio-urea-κS)(thio-cyanato-κN)copper(I).

Project description:The asymmetric unit of the title compound, [Cu(NCS)(C3H8N2S)(C27H26P2)], contains two independent mononuclear complex mol-ecules. In each, the Cu(I) ion exhibits a distorted tetra-hedral geometry by coordination with two P atoms from one 1,3-bis(diphenylphosphino)propane (dppm) ligand, one terminal S atom of one N,N'-di-methyl-thio-urea (dmtu) ligand and one terminal N atom of the thio-cyanato ligand. The dppp ligand is involved in a bidentate coordination mode with the Cu(I) ion, forming a six-membered CuP2C3 ring. In both mol-ecules, the coordination of the dmtu ligand is further stabilized by an intra-molecular N-H⋯N hydrogen bond with an S(6) graph-set motif. In the crystal, mol-ecules are linked by N-H⋯S hydrogen bonds forming a zigzag chain along the a-axis direction. In one independent mol-ecule, one of the phenyl rings of the dppp ligand is disordered over two sites with refined occupancies 0.639 (11):0.361 (11) and this corresponds with a mutual disorder of the dmtu ligand in the other independent mol-ecule giving the same ratio of refined occupancies. The structure was refined as a two-component inversion twin.

The CrC(4)P(2) coordination geometry at the Cr atom is distorted octa-hedral, with a P-Cr-P bite angle of 70.27 (2)°.
