Catena-Poly[[dibromidomercury(II)]-?-3,6-bis-(2-pyridyl-sulfan-yl)pyridazine-?N:N].

ABSTRACT: In the title coordination polymer, [HgBr(2)(C(14)H(10)N(4)S(2))](n), the Hg(II) atom is four-coordinated in a distorted tetra-hedral geometry by the two N atoms of the pyridyl groups of different 3,6-bis-(2-pyridyl-sulfan-yl)pyridazine ligands and two Br atoms. The bridging function of the cis ligands leads to a helical chain structure along [100].

catena-Poly[[μ(2)-aqua-diaqua-bis-(μ(4)-pyridazine-3,6-dicarboxyl-ato)tetra-lithium] monohydrate].

Project description:In the polymeric structure of the title compound {[Li(2)(C(6)H(2)N(2)O(4))(2)Li(H(2)O)(2)Li(H(2)O)]·H(2)O}(n), the coordination of two independent Li(I) ions is distorted trigonal-bipyramidal and that of the other two independent Li(I) ions is distorted tetra-hedral. The former two Li(I) ions are bridged by hetero-ring N atoms of two independent pyridazine-3,6-dicarboxyl-ate ligands, making a dimeric moiety. The carboxyl-ato-O atoms of both bidentate ligands bridge the dimers to adjacent independent aqua-coordinated Li(I) ions, forming mol-ecular ribbons. The latter are bridged by ligand carboxyl-ato and aqua O atoms, forming mol-ecular layers parallel to (100) which are held together by an extended system of O-H⋯O hydrogen bonds.

Project description:The asymmetric unit of the title compound, {[Cu(C(10)H(8)N(2)S(2))(2)(H(2)O)(2)](C(8)H(5)O(4))(2)·H(2)O}(n), contains one Cu(II) ion, two bridging di-4-pyridyl disulfide (4-DPDS) ligands of the same chirality, two coordinating water mol-ecules, two hydrogen phthalate anions and one uncoordinated water mol-ecule. The polymeric structure consists of two types of polymeric chains, each composed from repeated chiral rhomboids. The Cu(II) ions adopt a distorted octa-hedral coordination geometry and are coordinated by four pyridine N atoms and two water O atoms. The coordinated water mol-ecules and hydrogen phthalate anions are located between the repeated rhomboidal chains, and form hydrogen bonds with the coordinated water mol-ecules.

Project description:The asymmetric unit of the title salt, [Ag(C(14)H(14)N(4)O(2))(1.5)](CF(3)SO(3)), comprises a Ag(+) cation, three half-mol-ecules of N,N'-bis-(2-pyridyl-meth-yl)oxalamide (each of which is dis-posed about a centre of inversion) and a trifluoro-methane-sulfonate anion. Distinct coordination modes are found for the bridging ligands, i.e., a μ(2),κ(2)-bridging mode involving pyridine N atoms for one ligand, and a μ(2),κ(4)-bridging mode, employing both pyridine N and amide O atoms for the remaining ligands. The Ag(+) cations, which are in a distorted square-pyramidal coordination, and the ligands combine to form a two-dimensional array parallel to (101); these arrays are connected into a three-dimensional structure by trifluoro-methane-sulfonate anions via N-H⋯O, C-H⋯O, and C-F⋯O inter-actions.
