Crystal structure of poly[[aqua-(?-2,3-di-hydro-thieno[3,4-b][1,4]dioxine-5,7-di-carboxyl-ato-?²O⁵:O⁷)[?-di(pyridin-4-yl)sulfane-?²N:N']zinc] 0.26-hydrate].

ABSTRACT: The crystal structure of the title polymer, {[Zn(C₈H₄O₆S)(C₁₀H₈N₂S)(H₂O)]·0.26H₂O} _n , is characterized by a layered arrangement parallel to the ab plane. The zinc cation is five-coordinated in a slightly distorted trigonal-bipyramidal coordination environment defined by two pyridine ligands, two carboxyl-ate groups of two thio-phene di-carboxyl-ate ligands, and by one water mol-ecule. The ethyl-ene bridge in the dioxine ligand is disordered over two sets of sites [occupancy ratio 0.624?(9):0.376?(9)]. Several hydrogen-bonding inter-actions of the types O-H?O, C-H?O, C-H?S and C-H?N ensure the cohesion within the crystal structure.

Diethyl 2,3-dihydro-thieno[3,4-b]-1,4-dioxine-5,7-dicarboxyl-ate.

Project description:The title compound, C(12)H(14)O(6)S, is a dicarboxylic acid diethyl ester of 3,4-ethyl-enedioxy-thio-phene, which is a component of electrically conductive poly(3,4-ethyl-enedioxy-thio-phene) (PEDOT).

The mol-ecules form centrosymmetric dimers with an R(2) (2)(12) coupling by inter-molecular C-H⋯O hydrogen bonds [3.333 (5) Å] at the ethoxy-carbonyl groups. The dimer units are arranged to form a ribbon-like mol-ecular sheet.

Project description:In the title compound, C17H18O5S, an analogue of the potent anti-cancer agent combretastatin A-4, the alkene C=C bond has a cis conformation and the C-C=C-C torsion angle is 9.0 (3)°.

The C atoms of the two meta-meth-oxy groups are close to being coplanar with their attached benzene ring [displacements = -0.025 (2) and -0.196 (2) Å], whereas the C atom of the para-meth-oxy group is significantly displaced [by -1.107 (2) Å]. In the crystal, C-H⋯O hydrogen bonds link the mol-ecules into [0-11] chains, which feature two different types of R 2 (2)(6) loops.

Crystal structure and thermal properties of bis-[μ-2-(meth-oxy-carbonyl-hydrazinyl-idene)acetato-κ3 N 1,O:O]bis-[di-aqua-(thio-cyanato-κN)manganese(II)] tetra-hydrate.

Project description:The title compound, [Mn2(C4H5N2O4)2(NCS)2(H2O)4]·4H2O (I), exists as a centrosymmetric dimer. Each dimeric unit consists of tridentate (O,O,N)-chelating Schiff bases with symmetry-maintained μ-O-bridged carboxyl-ate anions, terminally bound thio-cyanate anions, and ligated and solvated water mol-ecules. The complex exhibits a distorted octa-hedron geometry and the centrosymmetric μ-O-bridged carboxyl-ate anions connect the two manganese atoms to form an M 2O2 ring. In the crystal, the mol-ecules are inter-linked via strong N-H⋯O and O-H⋯O hydrogen-bonding contacts and weak O-H⋯S inter-molecular inter-actions, forming a three-dimensional mol-ecular network.

Synthesis and crystal structure of catena-poly[cobalt(II)-di-μ-chlorido-μ-pyridazine-κ2N1:N2].

Project description:The reaction of cobalt dichloride hexa-hydrate with pyridazine leads to the formation of crystals of the title compound, [CoCl2(C4H4N2)]n. This compound is isotypic to a number of compounds with other divalent metal ions. Its asymmetric unit consists of a Co2+ atom (site symmetry 2/m), a chloride ion (site symmetry m) and a pyridazine mol-ecule (all atoms with site symmetry m). The Co2+ cations are coordinated by four chloride anions and two pyridazine ligands, generating trans-CoN4Cl2 octa-hedra, and are linked into [010] chains by pairs of μ-1,1-bridging chloride anions and bridging pyridazine ligands. In the crystal structure, the pyridazine ligands of neighboring chains are stacked onto each other, indicating π-π inter-actions. Powder X-ray diffraction proves that a pure crystalline phase was obtained. Differential thermonalysis coupled to thermogravimetry (DTA-TG) reveal that decomposition is observed at about 710 K. Magnetic measurements indicate low-temperature metamagnetic behavior as already observed in a related compound.

Poly[[(1,10-phenanthroline){μ(3)-2,2',2''-[1,3,5-triazine-2,4,6-triyltris(sulfane-diyl)]triacetato}-cadmium] 0.42-hydrate].

Project description:The asymmetric unit of the title complex, {[Cd(C(9)H(7)N(3)O(6)S(3))(C(12)H(8)N(2))]·0.42H(2)O}(n), contains a Cd(II) atom, one doubly deprotonated 2,2',2''-[1,3,5-triazine-2,4,6-triyltris(sulfanediyl)]triacetic acid ligand (HTTTA(2-)), a 1,10-phenanthroline (phen) ligand and a fractionally occupied water mol-ecule [site occupancy = 0.421 (15)]. The Cd(II) atom is six-coordinated within a distorted octa-hedral coordination geometry. Six coordination arises from four O atoms derived from three different HTTTA(2-) ligands, and two N atoms of the chelating phen mol-ecule. The incompletely deprotonated triazine ligand adopts a μ(3)-η(1):η(1):η(2) coordination mode, resulting in the formation of chains along the c axis based on Cd(2)O(2) dimeric units. Adjacent chains are stacked through π-π stacking [3.533 (2) Å between phen and triazine rings] and C-H⋯O inter-actions, forming supra-molecular sheets in the ab plane. Intra-and intermolecular O-H⋯O hydrogen bonds are also observed.

Tetra-aqua-bis-(pyridine-3-carbo-nitrile-κN 1)nickel(II) benzene-1,4-di-carboxyl-ate tetra-hydrate.

Project description:A nickel(II) terephthalate complex, viz. [Ni(C6H4N2)2(H2O)4](O2CC6H4CO2)·4H2O, has been synthesized and studied by single-crystal X-ray diffraction. It crystallizes in the triclinic space group P . The crystal structure shows an approximately octa-hedral coordination environment of the complex with the [Ni(H2O)4(3-NCpy)2]2+ (3-NCpy is pyridine-3-carbo-nitrile) cation associated with four free water mol-ecules and hydrogen bonded to a terephthalate dianion [graph set R 2 2(8)]. The supra-molecular structure of the compound is stabilized by a three-dimensional array of O-H⋯O and O-H⋯N hydrogen bonds, along with π-π stacked pyridine-3-carbo-nitrile rings and C-H⋯O inter-actions.

catena-Poly[[lithium-μ2-(di-hydrogen pyrazine-2,3,5,6-tetra-carboxyl-ato)-κ(6) O (2),N (1),O (6);O (3),N (4),O (5)-lithium-di-μ-aqua-κ(4) O:O] 2.5-hydrate].

Project description:The title coordination polymer, {[Li2(C8H2N2O8)(H2O)2]·2.5H2O} n , is built up from mol-ecular ribbons propagating in the c-axis direction of the ortho-rhom-bic unit cell; the ligand bridges two Li(+) ions using both its N,O,O'-bonding sites and adjacent Li(+) ions are bridged by pairs of water mol-ecules. The coordination geometry of the metal ion is distorted trigonal bipyramidal, with the ligand O atoms in the axial sites. Two of the carboxyl-ate groups of the ligand remain protonated and form short symmetric O-H⋯O hydrogen bonds. In the crystal, the ribbons inter-act via a network of O-H⋯O hydrogen bonds in which coordinating water mol-ecules act as donors and carboxyl-ate O atoms within adjacent ribbons act as acceptors, giving rise to a three-dimensional framework. O-H⋯N inter-actions are also observed. The asymmetric unit contains quarter of the ligand and the complete ligand has 2/m symmetry; the Li(+) ion lies on a special position with m.. site symmetry. Both bridging water mol-ecules have m2m site symmetry and both lattice water mol-ecules have m.. site symmetry; one of the latter was modelled with a site occupancy of 0.25.
