Crystal structure of bis-(piperazin-1-ium-?N4)bis-(thio-sulfato-?S)zinc(II) dihydrate.

ABSTRACT: In the title compound, [Zn(C4H11N2)2(S2O3)2]·2H2O, two thio-sulfate ions coordinate to the zinc(II) atom through the terminal S atoms. The tetra-hedral coordination around the ZnII ion is completed by ligating to two N atoms of two piperazinium ions. The remaining two N atoms of the piperazinium ions are diprotonated and do not coordinate to the metal centre. In the crystal, however, they are involved in N-H?Owater and N-H?Osulfato hydrogen bonds. Together, a series of N-H?O and O-H?O hydrogen bonds, involving the O atoms of the thio-sulfate ions and the water mol-ecules as acceptors and the hydrogen atoms of the piperazinium ions and the water mol-ecules as donors, form a three-dimensional supra-molecuar structure. Within this framework there are a number of intra- and inter-molecular C-H?O and C-H?S contacts present.

Tetra-aqua-bis-(piperazin-1-ium)cobalt(II) bis-(sulfate) dihydrate.

Project description:In the centrosymmetric title compound, [Co(C4H11N2)2(H2O)4](SO4)2·2H2O, the Co(II) atom is coordinated in a distorted octa-hedral geometry by four water O atoms and two piperazinium N atoms. These four water O atoms define an equatorial plane with a maximum deviation of 0.0384 (1) Å while the two piperazinium N atoms complete the octa-hedron in the axial positions. Neighboring complex mol-ecules and sulfate anions are connected through an extensive network of N-H⋯O and O-H⋯O hydrogen bonds, which link the different chemical species into layers in the ab plane. Additional Owater-H⋯O hydrogen bonds involving the non-coordinating water mol-ecules and C-H⋯O inter-actions connect these layers into a three-dimensional supra-molecular structure.

Tetra-aqua-bis-(thio-urea-κS)cadmium(II) triaqua-tris(thio-urea-κS)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).

Crystal structure of bis-(1,4-di-aza-bicyclo-[2.2.2]octan-1-ium) thio-sulfate dihydrate.

Project description:The crystal structure of the hydrated title salt, 2C6H13N2 (+)·S2O3 (2-)·2H2O, contains a centrosymmetric cyclic motif of eight hydrogen-bonded mol-ecular subunits. Two DABCOH(+) cations (DABCO = 1,4-di-aza-bicyclo-[2.2.2]octa-ne) are linked to two water mol-ecules and two thio-sulfate anions via O-H⋯N and O-H⋯O hydrogen bonds, respectively. Two other water mol-ecules close the cyclic motif through O-H⋯O contacts to the first two water mol-ecules and to the two thio-sulfate anions. A second pair of DABCOH(+) cations is N-H⋯O hydrogen bonded to the two anions and is pendant to the ring. Adjacent cyclic motifs are bridged into a block-like arrangement extending along [100] through O-H⋯O inter-actions involving the second pair of water mol-ecules and neighbouring thio-sulfate anions.

All H atoms of the thio-urea ligands are involved in N-H⋯O and N-H⋯S hydrogen bonds, leading to a three-dimensional network.

(Tetra-oxidoselenato-κO)tris-(thio-urea-κS)zinc(II).

Project description: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.

Bis(?-3-nitro-phthalato-?O:O)bis-[(thio-urea-?S)zinc] dihydrate.

Project description:In the title complex, [Zn(2)(C(8)H(3)NO(6))(2)(CH(4)N(2)S)(4)]·2H(2)O, the carboxyl-ate groups of the 3-nitro-phthalate ligands coordinate in a bis-monodentate mode to the Zn(II) cations. This results in the formation of a centrosymmetric dimer containing two Zn(II) cations with distorted tetra-hedral geometries provided by the O atoms of two different 3-nitro-phthalate dianions and the S atoms of two non-equivalent coordinated thio-urea mol-ecules. The crystal structure exhibits N-H?O and O-H?O hydrogen bonds which link the dimers into a three-dimensional network.
