Catena-Poly[[(5,5'-dimethyl-2,2'-bi-pyridine-?N,N')cadmium(II)]-di-?-iodido].

ABSTRACT: In the title coordination polymer, [CdI(2)(C(12)H(12)N(2))](n), the Cd(2+) ion lies on a twofold rotation axis: it is six-coordinated in a distorted cis-CdN(2)I(4) octa-hedral geometry by two N atoms from a chelating 5,5'-dimethyl-2,2'-bipyridine ligands and four bridging iodide anions. The bridging function of the iodide ions leads to a chain structure propagating in [001].

Project description:The asymmetric unit of the title compound, [CdCl(2)(C(12)H(12)N(2))](n), contains one half-mol-ecule; a twofold rotation axis passes through the Cd atom. The Cd(II) atom is six-coordinated in a distorted octa-hedral configuration by two N atoms from 2,2'-bipyridine-5,5'-dimethyl and four bridging Cl atoms.

(5,5'-Dimethyl-2,2'-bipyridine)-iodido-trimethyl-platinum(IV).

Project description:In the title compound, [Pt(CH(3))(3)I(C(12)H(12)N(2))], the Pt(IV) atom is six-coordinated in a slightly distorted octa-hedral configuration with one CH(3) group and the I atom forming a near perpendicular axis relative to the square plane formed by the bipyridine ligand and the two remaining CH(3) groups. The CH(3) group trans to the I atom has a slightly elongated bond to Pt compared to the other CH(3) groups, indicating a difference in trans influence between iodine and the bipyridine ligand.

catena-Poly[[di-?-iodido-dicopper(I)(Cu-Cu)]bis-(?-4,4'-di-3-pyridyl-2,2'-disulfanediyldipyrimidine)].

Project description:The title complex, [Cu(2)I(2)(C(18)H(12)N(6)S(2))(2)](n), contains a Cu(2)I(2) core with a Cu-Cu distance of 2.6935?(14)?Å. The Cu(I) atom is coordinated by two bridging 4,4'-di-3-pyridyl-2,2'-disulfanediyldipyrimidine ligands and two bridging I atoms, forming a double chain.

catena-Poly[[aqua-(5,5'-dimethyl-2,2'-bipyridine-?N,N')copper(II)]-?-2,2'-oxydibenzoato-?O:O'].

Project description:In the title compound, [Cu(C(14)H(8)O(5))(C(12)H(12)N(2))(H(2)O)](n), the Cu(II) ion is penta-coordinated in a square-pyramidal geometry. Two N atoms of the chelating 5,5'-dimethyl-2,2'-bipyridine (dbp) ligand and two O atoms of two different 2,2'-oxydibenzoic (odb) ligands occupy the basal plane while the water O atom completes the square-pyramidal geometry at the apical site. The non-water N(2)O(2) donor atoms are nearly coplanar, with a mean deviation from the least-squares plane of 0.0518?(11)?Å and the Cu atom is displaced by 0.1507?(11)?Å from this plane towards the apical water O atom. Further coordination via the 2,2'-oxydibenzoate anions forms a one-dimensional coordination polymer extending parallel to [010]. In the crystal structure, O-H?O hydrogen bonds link the mol-ecules into a two-dimensional supra-molecular structure.

Crystal structure of catena-poly[[chlorido-(4,4'-dimethyl-2,2'-bi-pyridine-κ(2) N,N')copper(II)]-μ-chlorido].

Project description:The title compound, [CuCl2(C12H12N2)] n , was obtained via a DMSO-mediated dehydration of Cu(4,4'-dimethyl-2,2'-bi-pyridine)-copper(II)·0.25H2O. The central Cu(II) atom is coordinated in a distorted trigonal-bipyramidal geometry by two N atoms of a chelating 4,4'-dimethyl-2,2'-bi-pyridine ligand [average Cu-N = 2.03 (3) Å] and three Cl atoms, one terminal with a short Cu-Cl bond of 2.2506 (10) Å, and two symmetry-equivalent and bridging bonds. The bridging Cl atom links the Cu(II) ions into chains parallel to [001] via one medium and one long Cu-Cl bond [2.3320 (10) and 2.5623 (9) Å]. The structure displays both inter- and intra-molecular C-H⋯Cl hydrogen bonding.

Crystal structure of poly[[(2,2'-bi-pyridine)manganese(II)]-di-?-thio-cyanato].

Project description:In the crystal structure of the polymeric title compound, [Mn(NCS)2(C10H8N2)] n , the Mn(II) cations are coordinated by one chelating 2,2'-bi-pyridine ligand and four thio-cyanate anions (two N- and two S-coordinating), forming a distorted [MnN4S2] octa-hedron. The asymmetric unit consists of one manganese cation located on a twofold rotation axis and half of a 2,2'-bi-pyridine ligand, the other half being generated by the same twofold rotation axis, as well as one thio-cyanate anion in a general position. The Mn(II) cations are linked by two pairs of ?1,3-bridging thio-cyanate ligands into chains along the c axis; because the N atoms of the 2,2'-bi-pyridine ligands, as well as the N and the S atoms of the thio-cyanate anions, are each cis-coordinating, these chains show a zigzag arrangement.

Syntheses, crystal structures and thermal properties of catena-poly[cadmium(II)-di-μ-bromido-μ-pyridazine-κ2N1:N2] and catena-poly[cadmium(II)-di-μ-iodido-μ-pyridazine-κ2N1:N2]

Project description:In the crystal structures of the title compounds, the cadmium cations are octahedrally coordinated by four halide anions and two pyridazine ligands in a trans-CdX4N2 (X = Br, I) arrangement and are linked into chains by the halide anions and the pyridazine ligands. The reactions of cadmium bromide and cadmium iodide with pyridazine (C4H4N2) in ethanol under solvothermal conditions led to the formation of crystals of [CdBr2(pyridazine)]n (1) and [CdI2(pyridazine)]n (2), which were characterized by single-crystal X-ray diffraction. The asymmetric units of both compounds consist of a cadmium cation located on the intersection point of a twofold screw axis and a mirror plane (2/m), a halide anion that is located on a mirror plane and a pyridazine ligand, with all atoms occupying Wyckoff position 4e (mm2). These compounds are isotypic and consist of cadmium cations that are octahedrally coordinated by four halide anions and two pyridazine ligands and are linked into [100] chains by pairs of μ-1,1-bridging halide anions and bridging pyridazine ligands. In the crystals, the pyridazine ligands of neighboring chains are stacked onto each other, indicating π–π interactions. Larger amounts of pure samples can also be obtained by stirring at room-temperature, as proven by powder X-ray diffraction. Measurements using thermogravimetry and differential thermoanalysis (TG-DTA) reveal that upon heating all the pyridiazine ligands are removed in one step, which leads to the formation of CdBr2 or CdI2.
