(Tetra-oxidoselenato-?O)tris-(thio-urea-?S)zinc(II).

ABSTRACT: The title structure, [Zn(SeO(4))(CH(4)N(2)S)(3)], is isomorphous with sulfatotris(thio-urea)zinc(II). In both structures, the Zn(2+) cation is coordinated in a tetra-hedral geometry. The corresponding intra-molecular distances are quite similar except for the Se-O and S-O distances. Although the hydrogen-bonding patterns are similar, there are some differences; in the title structure all the H atoms are involved in the hydrogen-bond pattern, in contrast to the situation in sulfatotris(thio-urea)zinc(II). No reproducible anomalies were detected by differential scanning calorimetry in the range 93-463?K until decomposition started at the higher temperature.

(Thio-cyanato-κS)-tris-(thio-urea-κS)mercury(II) chloride.

Project description:In the title salt, [Hg(NCS)(CH4N2S)3]Cl, the Hg(2+) ion is coordinated in a severely distorted tetra-hedral manner by three thio-urea groups and one thio-cyanate anion through their S atoms. The S-Hg-S angles vary widely from 87.39 (5) to 128.02 (4)°. Weak intra-molecular N-H⋯S hydrogen bonds are observed, which form S(6) ring motifs. In the crystal, the ions are linked by N-H⋯N and weak N-H⋯Cl inter-actions, generating a three-dimensional network.

Bis(acetato-κO)bis-(thio-urea-κS)cobalt(II).

Project description:The title compound, [Co(CH3COO)2(CH4N2S)2], is isotypic with the corresponding Zn(II) complex.

Tetra-aqua-bis-(thio-urea-?S)cadmium(II) triaqua-tris(thio-urea-?S)cadmium(II) disulfate.

Project description:The title compound, [Cd(CH(4)N(2)S)(2)(H(2)O)(4)][Cd(CH(4)N(2)S)(3)(H(2)O)(3)](SO(4))(2), contains two mol-ecules of each of the Cd complexes and four sulfate ions in the asymmetric unit: all the Cd atoms exhibit distorted octa-hedral geometries. The Cd-S and Cd-O bond lengths around the Cd atoms in the bis-(thio-urea) cations are in the ranges 2.580?(4)-2.599?(4) and 2.323?(8)-2.421?(9)?Å, respectively, and the S atoms are in a cis orientation. In the tris-(thio-urea) cations, the corresponding bond lengths around the Cd atoms are slightly longer and are in the ranges 2.559?(4)-2.706?(3) and 2.303?(7)-2.480?(10)?Å, respectively, and the S atoms are in a fac disposition. The crystal structure features numerous N-H?O, N-H?N, O-H?O and O-H?N hydrogen bonds. Two O atoms of a sulfate anion were found to be disordered over two orientations in a 0.620?(9):0.380?(9) ratio. The crystal studied was a racemic twin with BASF = 0.17?(5).

Poly[bis-(methanol-κO)tris-(μ-pyrimidine-κN:N')tetra-kis(thio-cyanato-κN)dinickel(II)].

Project description:In the crystal structure of the title compound, [Ni(2)(NCS)(4)(C(4)H(4)N(2))(3)(CH(3)OH)(2)](n), each nickel(II) cation is coordinated by three N-bonded pyrimidine ligands, two N-bonded thio-cyanate anions and one O-bonded methanol mol-ecule in a distorted octa-hedral environment. The asymmetric unit consists of one nickel cation, two thio-cyanate anions and one methanol mol-ecule in general positions, as well as one pyrimidine ligand located around a twofold rotation axis. The crystal structure consists of μ-N:N' pyrimidine-bridged zigzag-like nickel thio-cyanate chains; these are further linked by μ-N:N-bridging pyrimidine ligands into layers which are stacked perpendicular to the b axis. The layers are connected via weak O-H⋯S hydrogen bonding.
