The asymmetric unit in the title compound, C(5)H(5)NO, comprises two independent but virtually identical mol-ecules of 2-pyridone, and represents a monoclinic polymorph of the previously reported ortho-rhom-bic (P2(1)2(1)2(1)) form [Penfold (1953 ▶). Acta Cryst.6, 591-600; Ohms et al. (1984 ▶). Z. Kristallogr.169, 185-200; Yang & Craven (1998 ▶). Acta(More)
The asymmetric unit of the title compound, [Cd2(C12H10N2)3(C6H12NOS2)4]·4C2H3N, comprises a Cd(II) atom, two di-thio-carbamate (dtc) anions, one and a half trans-1,2-dipyridin-4-yl-ethyl-ene (bpe) mol-ecules and two aceto-nitrile solvent mol-ecules. The full binuclear complex is generated by the application of a centre of inversion. The dtc ligands are(More)
The dinuclear title solvate, [Zn(2)(C(5)H(10)NS(2))(4)(C(12)H(10)N(2))]·CHCl(3), features two five-coordinate Zn atoms; both coordination polyhedra are distorted, but one has an NS(4) donor set approximating to a square pyramid (with the N atom in the apical site), while the other is closer to a ZnNS(4) trigonal-bipyramidal arrangement (with the N atom in(More)
The asymmetric unit of the title compound, [Zn(C4H8NOS2)2(C18H12N6)] 1.5C4H8O2, comprises a Zn-containing molecule and one and a half dioxane molecules as one of the solvent molecules is located about a crystallographic inversion centre. The approximately square-pyramidal N3S2 donor set is defined by two monodentate dithiocarbamate ligands and two pyridine(More)
The common feature of the mol-ecular structures of the title compounds, [Zn(C5H10NS2)2(C5H5NO)], (I), and [Zn(C4H8NOS2)2(C5H5NO)], (II), are NS4 donor sets derived from N-bound hy-droxy-pyridyl ligands and asymmetrically chelating di-thio-carbamate ligands. The resulting coordination geometries are highly distorted, being inter-mediate between square(More)
The asymmetric unit of the title co-crystal, C(14)H(14)N(4)S(2)·C(14)H(10)O(4)S(2), comprises a twisted 2,2'-(disulfanedi-yl)dibenzoic acid mol-ecule [dihedral angle between the benzene rings = 83.53 (14)°] and a U-shaped mol-ecule of N,N'-bis-(4-pyridyl-meth-yl)ethane-dithio-amide in which intra-molecular N-H⋯S hydrogen bonds are observed. Two mol-ecules(More)
The dinuclear centrosymmetric title compound, [Sn(2)(C(6)H(5))(6)(C(6)H(8)N(2)S(4))]·CH(2)Cl(2), features a distorted cis-trigonal-bipyramidal coordination geometry for Sn based on a C(3)S(2) donor set. The dinuclear mol-ecule lies across a centre of inversion. The solvent dichloro-methane mol-ecule is disordered about a centre of inversion.
The asymmetric unit of title salt co-crystal, [K(C9H11N2S2)(C12H24O6)], comprises a K(+) cation, an (-)S2CN(Et)py anion and a 18-crown-6 mol-ecule. Substantial delocalization of π-electron density is evident in the di-thio-carbamate anion, as indicated by the equivalent C-S bond lengths. The K(+) cation sits within an O6S2 donor set lying 0.7506 (6) Å out(More)
New solvent-separated ion-pair compounds and extended structures containing ytterbium(II)-transition metal isocarbonyl linkages were synthesized. [Yb(THF)6][M(CO)5]2 (1, M = Mn; 2, M = Re) were prepared via transmetalation reactions between Yb metal and Hg[M(CO)5]2 in THF. Reflux of 1 in Et2O afforded {Yb(THF)2(Et2O)2[(mu-CO)2Mn(CO)3]2}infinity (3) which is(More)
In the title compound, K(+)·C(14)H(9)O(4)S(2) (-)·C(14)H(10)O(4)S(2), the hydrogen 2,2'-dithio-dibenzoate and 2,2'-disulfane-diyl-di-ben-zoic acid species combine to provide an O(6)S(2) donor set to the potassium cation based on a cubic geometry. K⋯S [3.1733 (7) and 3.5499 (8) Å] and K⋯O [2.6586 (16)-3.0661 (15) Å)] inter-actions, coupled with O-H⋯O(More)
