Synthesis, crystal structure and thermal decomposition of the new cadmium selenite chloride, Cd4(SeO3)2OCl2.

ABSTRACT: A synthetic study in the Cd-Se-O-Cl system led to formation of the new oxochloride compound Cd4(SeO3)2OCl2 via solid state reactions. The compound crystallizes in the orthorhombic space group Fmmm with cell parameters a?=?7.3610(3) Å, b?=?15.4936(2) Å, c?=?17.5603(3) Å, Z?=?8, S?=?0.969, F(000)?=?2800, R?=?0.0185, Rw?=?0.0384. Single crystal X-ray data were collected at 293 K. The crystal structure can be considered as layered and the building units are distorted [Cd(1)O6] octahedra, distorted [Cd(2)O8] cubes, irregular [Cd(3)O4Cl2] polyhedra and SeO3E trigonal pyramids. There are two crystallographically unique Cl atoms that both are half occupied. Thermogravimetric studies show that the compound starts to decompose at 500°C. The crystal structure of the new compound is closely related to the previously described compound Cd4(SeO3)2Cl4(H2O).

Synthesis, crystal structure, and thermal decomposition of the cobalt(II) complex with 2-picolinic acid.

Project description:The cobalt(II) complex of 2-picolinic acid (Hpic), namely, [Co(pic)₂(H₂O)₂] · 2H₂O, was synthesized with the reaction of cobalt acetate and 2-picolinic acid as the reactants by solid-solid reaction at room temperature. The composition and structure of the complex were characterized by elemental analysis, infrared spectroscopy, single crystal X-ray diffraction, and thermogravimetry-differential scanning calorimetry (TG-DSC). The crystal structure of the complex belongs to monoclinic system and space group P2(1)/n, with cell parameters of a = 9.8468(7) Å, b = 5.2013(4) Å, c = 14.6041(15) Å, β = 111.745(6)°, V = 747.96(11) Å³, Z = 2, D(c) = 1.666 g cm⁻³, R₁ = 0.0297, and wR₂ = 0.0831. In the title complex, the Co(II) ion is six-coordinated by two pyridine N atoms and two carboxyl O atoms from two 2-picolinic acid anions, and two O atoms from two H2O molecules, and forming a slightly distorted octahedral geometry. The thermal decomposition processes of the complex under nitrogen include dehydration and pyrolysis of the ligand, and the final residue is cobalt oxalate at about 450°C.

Hydro-thermal synthesis and crystal structure of a new lanthanum(III) coordination polymer with fumaric acid.

Project description:The title compound, poly[di-aqua-tris-(?4-but-2-enedioato)(?2-but-2-enedioic acid)dilanthanum(III)], [La2(C4H2O4)3(C4H4O4)(H2O)2] n , was synthesized by the reaction of lanthanum chloride penta-hydrate with fumaric acid under hydro-thermal conditions. The asymmetric unit comprises an La(III) cation, one and a half fumarate dianions (L (2-)), one a half-mol-ecule of fumaric acid (H2 L) and one coordinated water mol-ecule. Each La(III) cation has the same nine-coordinate environment and is surrounded by eight O atoms from seven distinct fumarate moieties, including one proton-ated fumarate unit and one water mol-ecule in a distorted tricapped trigonal-prismatic environment. The LaO8(H2O) polyhedra centres are edge-shared through three carboxyl-ate bridges of the fumarate ligand, forming chains in three dimensions to construct the MOF. The crystal structure is stabilized by O-H?O hydrogen-bond inter-actions between the coordin-ated water mol-ecule and the carboxyl-ate O atoms, and also between oxygen atoms of fumaric acid.

Crystal structure of 4-carbamoylpyridinium chloride.

Project description:The hydro-chloride salt of isonicotinamide, C6H7N2O(+)·Cl(-), has been synthesized from a dilute solution of hydro-chloric acid in aceto-nitrile. The compound displays monoclinic symmetry (space group C2/c) at 150?K, similar to the related hydro-chloride salt of nicotinamide. The asymmetric unit contains one protonated isonicotinamide mol-ecule and a chloride anion. An array of hydrogen-bonding inter-actions, including a peculiar bifurcated pyridinium-chloride inter-action, results in linear chains running almost perpendicularly in the [150] and [1-50] directions within the structure. A description of the hydrogen-bonding network and comparison with similar compounds are presented.

Synthesis, spectroscopic, thermal, crystal structure properties, and characterization of new Hofmann-T<sub>d</sub>-type complexes with 3-aminopyridine.

Project description:In this study, synthesis of two new tetracyanocadmate(II) and tetracyanozincate(II) complexes based on 3-aminopyridine (3AP) and investigation of their structural properties were reported. These complexes were characterized by using vibration spectroscopy, elemental, thermal analysis and single crystal X-ray diffraction (SC-XRD) techniques. Investigation of the elemental, spectral and single crystal data of these complexes showed that the formulas [Cd(3AP)2Zn(μ4-CN)4]n (1) and [Cd(3AP)2Cd(μ4-CN)4]n (2) fully explained their crystal structure. General information about the structural and chemical properties of these complexes obtained in single crystal form was obtained by observing the changes in the characteristic peaks of the 3AP with the [Zn(μ4-CN)4]2- and [Cd(μ4-CN)4]2- structures that make up these complexes. The behaviors of these complexes against changes in temperature were obtained by examining the temperature-dependent changes of their mass. The asymmetric unit of the heterometallic complexes 1 and 2 consist of half Cd(II) ion, half M ion [M = Zn1 in 1 and Cd2 in 2], two cyanide ligands and one 3AP.

Crystal structure, thermal and fluorescence properties of 2,2':6',2''-terpyridine-1,1',1''-triium tetra-chlorido-nickelate(II) chloride.

Project description:The title compound, (C15H14N3)[NiCl4]Cl, comprises an NiII cation tetra-hedrally coordinated by four chloride anions, a non-coordinating chloride anion and an essentially planar terpyridinium trication (tpyH33+), in which the central pyridinium ring forms dihedral angles of 5.7?(2) and 6.0?(2)° with the peripheral pyridinium rings. Three inter-species N-H?Cl hydrogen bonds are formed with the Cl- anion, which also forms a link between the (tpyH33+) cations through an aromatic C-H?Cl inter-action, forming a zigzag chain extending along the 21 (b) screw axis. Two of the anionic Cl atoms of the [NiCl4]2- anions form Ni-Cl?? inter-actions with separate pyridinium rings [Ni?Cg = 3.669?(3) and 3.916?(4)?Å]. In the crystal, successive undulating inorganic and organic layers are formed, extending across the (100) plane. Thermogravimetric and differential thermal analysis (TGA/DTA) indicate that the compound starts to decompose at 313?K and may be a candidate for use as a blue-light luminescent material.

Crystal structure of hy-droxy scandium nitrate chloride.

Project description:Each Sc3+ ion in the title salt, di-?-hydroxido-bis-[tri-aqua-(nitrato-?2 O,O')scandium(III)] dichloride, [Sc2(NO3)2(OH)2(H2O)6]Cl2, is coordinated by a nitrate anion, two hydroxide ions and three water mol-ecules to generate a distorted penta-gonal-bipyramidal ScO7 coordination polyhedron. The complete {[(NO3)(?-OH)Sc(H2O)3]2}2+ ion is generated by crystallographic inversion symmetry. The nitrate anion binds in a bidentate fashion whereas the hydroxide ions are bridged between two Sc centers. Two charge-balancing Cl- ions are located in the outer sphere. In the extended structure, O-H?O and O-H?Cl hydrogen bonds connect the components into a three-dimensional network.

Crystal structure of vilazodone hydro-chloride methanol monosolvate.

Project description:In the title compound, C26H28N5O2+·Cl-·CH3OH {systematic name: 4-(2-carbamoyl-1-benzo-furan-5-yl)-1-[4-(5-cyano-1H-indol-3-yl)but-yl]piperazin-1-ium chloride methanol monosolvate}, the protonated piperazine ring adopts a chair conformation. The indole ring plane is nearly perpendicular to the benzo-furan ring system, with a dihedral angle of 85.77?(2)°. In the crystal, the organic cations, Cl- anions and methanol solvent mol-ecules are linked by classical N-H?O and N-H?Cl hydrogen bonds, and weak C-H?O and C-H?? inter-actions into a three-dimensional supra-molecular architecture.

Synthesis, decomposition studies and crystal structure of a three-dimensional CuCN network structure with protonated N-methylethanolamine as the guest cation.

Project description:The compound poly[2-hydroxy-N-methylethan-1-aminium [?3-cyanido-?3C:C:N-di-?-cyanido-?4C:N-dicuprate(I)]], {(C3H10NO)[Cu2(CN)3]}n or [meoenH]Cu2(CN)3, crystallizes in the tetragonal space group P43. The structure consists of a three-dimensional (3D) anionic CuICN network with noncoordinated protonated N-methylethanolamine cations providing charge neutrality. Pairs of cuprophilic Cu atoms are bridged by the C atoms of ?3-cyanide ligands, which link these units into a 43 spiral along the c axis. The spirals are linked together into a 3D anionic network by the two other cyanide groups. The cationic moieties are linked into their own 43 spiral via N-H...O and O-H...O hydrogen bonds, and the cations interact with the 3D network via an unusual pair of N-H...N hydrogen bonds to one of the ?2-cyanide groups. Thermogravimetric analysis indicates an initial loss of the base cation and one cyanide as HCN at temperatures in the range 130-250?°C to form CuCN. We show how loss of a specific cyanide group from the 3D CuCN structure could form the linear CuCN structure. Further heating leaves a residue of elemental copper, isolated as the oxide.
