Catena-Poly[[[bis-(thio-urea-κS)copper(I)]-μ-thio-urea-κS:S] iodide acetonitrile hemisolvate].

ABSTRACT: The title complex, {[Cu(CH(4)N(2)S)(3)]I·0.5CH(3)CN}(n), was formed by the reaction of CuI and thio-urea in acetonitrile. There are two independent Cu(I) ions in the asymmetric unit which are coordinated by two terminal and two bridging thio-urea ligands to form a one-dimensional helical chain structure progagating in the a-axis direction. Each Cu(I) ion is in a distorted tetra-hedral coordination environment. The crystal structure is stabilized by weak N-H⋯S and N-H⋯I hydrogen bonds.

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).

catena-Poly[[(2,2'-bipyridine-κN,N')copper(I)]-μ-cyanido-κC:N-[(2,2'-bipyridine-κN,N')copper(I)]-μ-thio-cyanato-κS:N].

Project description:The title compound, [Cu(2)(CN)(SCN)(C(10)H(8)N(2))(2)](n), contains two crystallographically independent Cu(I) atoms, each in a distorted tetra-hedral geometry. Each Cu atom is coordinated by a bidentate chelating 2,2'-bipyridine ligand. A bridging cyanide anion links the two Cu(2,2'-bipyridine) units to form a binuclear unit. Adjacent binuclear units are connected by a thio-cyanate anion into a one-dimensional helical chain along [010]. The cyanide anion is disordered, with each site occupied by both C and N atoms in an occupancy ratio of 0.61 (5):0.39 (5). The S atom of the thio-cyanate anion is also disordered over two sites, with occupancy factors of 0.61 (3) and 0.39 (3). There are π-π inter-actions between the pyridyl rings of neighbouring chains [centroid-centroid distance = 3.82 (1) Å].

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.

Project description:In the title compound, [Ni(NCS)(2)(CH(3)CN)(2)](n), the Ni(II) cation is coordinated by two N-bonded and two S-bonded thio-cyanate anions, as well as two acetonitrile mol-ecules in an octa-hedral NiN(4)S(2) coordination mode. The asymmetric unit comprises one nickel cation, two thio-cyanate anions and two actonitrile mol-ecules. In the crystal, the Ni(II) cations are connected by bridging thio-cyanate anions into a three-dimensional coordination network.

Redetermination of catena-poly[[chlorido-(thio-urea-?S)copper(I)]-?-thio-urea-?S:S] at 100?K.

Project description:The structure of the polymeric title compound, [CuCl(CH(4)N(2)S)(2)](n), has been redetermined to modern standards of precision with anisotropic refinement and location of the H atoms. The previous structure report [Spofford & Amma (1970 ?). Acta Cryst. B26, 1474-1483] is generally confirmed to higher precision [typical Cu-S bond length s.u. values = 0.005 (old) and 0.001?Å (new)]. The asymmetric unit contains two formula units, with both Cu(I) atoms coordinated by one terminal S atom and two bridging S atoms of thio-urea ligands. This connectivity leads to polymeric [100] chains in the crystal. If very long contacts to nearby chloride ions [2.8687?(9) and 3.1394?(12)?Å] are considered to be bonding, then very distorted CuS(3)Cl tetra-hedral coordination polyhedra arise. The crystal structure is consolidated by weak intra- and inter-chain N-H?S and N-H?Cl hydrogen bonds.

catena-Poly[[bis-(pyridine-κN)cadmium]-di-μ(2)-thio-cyanato-κN:S;κS:N].

Project description:The asymmetric unit of the title compound, [Cd(NCS)(2)(C(5)H(5)N)(2)](n), consists of two crystallographically independent Cd(II) cations, four thio-cyanato anions and four pyridine ligands. The Cd(II) atoms are each coordinated by four N atoms from two pyridine ligands and two thio-cyanato anions, each in a mutually cis orientation, and by two S atoms from two adjacent thio-cyanato anions within a slightly distorted octa-hedral coordination environment. The Cd(II) atoms are μ-1,3-bridged via the thio-cyanato anions into polymeric chains parallel to [001]. The Cd(II)⋯Cd(II) intra-chain separations range between 5.9688 (6) and 6.0195 (6) Å, whereas the shortest Cd(II)⋯Cd(II) inter-chain separations are 7.8272 (7) and 8.6312 (6) Å.

Chlorido(1,3-dimethyl-thio-urea-?S)bis-(triphenyl-phosphine-?P)copper(I) acetonitrile hemisolvate.

Project description:The title compound, [CuCl(C(3)H(8)N(2)S)(C(18)H(15)P)(2)]·0.5CH(3)CN, was prepared by the reaction of copper(I) chloride with 1,3-dimethyl-thio-urea (dmtu) and triphenyl-phosphine (PPh(3)) in acetonitrile. The Cu(I) atom has a distorted tetra-hedral environment formed by two P atoms from triphenyl-phosphine, one S atom from the dmtu ligand and one Cl atom. In addition, the mol-ecules exhibit intra- and inter-molecular N-H?Cl inter-actions.

catena-Poly[copper(I)-bis(μ-trifluoro-methane-sulfonato-κO:O')-copper(I)-bis(μ-trimethyl trithio-phosphite)-κP:S;κS:P].

Project description:The title compound, [Cu(2)(CF(3)SO(3))(2)(C(3)H(9)PS(3))(2)](n), crystallizes as infinite chains in which two trimethyl trithio-phosphite ligands and two trifluoro-methane-sulfonate anions bridge the essentially tetra-hedrally coordinated Cu(I) ions in an alternating fashion. The P and one S atom of each trimethyl trithio-phosphite ligand are employed for coordination. The mol-ecular structure exhibits the rare motif of copper(I) bridged by two trifluoro-methane-sulfonate anions generating eight-membered rings.

μ(2)-Oxalato-bis-[triphen-yl(thio-urea-κS)tin(IV)].

Project description:The asymmetric unit of the binuclear title compound, [Sn(2)(C(2)O(4))(C(6)H(5))(6)(CH(4)N(2)S)(2)], consists of one half of the organotin(IV) mol-ecule. The remainder is generated by a twofold rotation axis passing through the mid-point of the oxalate C-C bond. The Sn(IV) atom exhibits a distorted trigonal-bipyramidal coordination environment with the phenyl groups in equatorial positions and the thio-urea and the monodentately bridging oxalate anion in axial positions. The mol-ecules are linked through N-H⋯O hydrogen bonds involving the amino group of the thio-urea ligand and the uncoordinating oxalate O atoms, forming layers parallel to (001). Weak C-H⋯O inter-actions are also present.
