Catena-Poly[di-?3-bromido-hexa-?2-bromido-dibromidobis(O-methyl pyridine-2-carboximidate-?(2) N,N')penta-mercury(II)].

ABSTRACT: The title compound, [Hg5Br10(C7H8N2O)2] n , contains two ?3-bridging Br atoms, six ?2-bridging Br atoms and two terminal Br atoms. One Hg(II) atom, lying on an inversion center, adopts a distorted octa-hedral geometry defined by six Br atoms. Two Hg(II) atoms adopt a distorted square-pyramidal geometry by five Br atoms and the other two Hg(II) atoms have a distorted tetra-hedral geometry by two N atoms from a chelating O-methyl pyridine-2-carboximidate ligand and two Br atoms. The Br atoms link the Hg(II) atoms into a ribbon structure along [100].

catena-Poly[[bis-(pyrazine-2-carbox-amide-κN)mercury(II)]-di-μ-bromido].

Project description:In the crystal structure of the title compound, [HgBr(2)(C(5)H(5)N(3)O)(2)](n), the Hg(II) cation is located on an inversion center and is coordinated by two N atoms from the pyrazine rings and four bridging Br(-) anions in a distorted octa-hedral geometry. The Br(-) anions bridge the Hg(II) cations with significantly different Hg-Br bond distances of 2.4775 (8) and 3.1122 (8) Å, forming polymeric chains running along the a axis. Inter-molecular N-H⋯O and N-H⋯N hydrogen bonds are effective in the stabilization of the crystal structure.

catena-Poly[[(N,N-di-methyl-cyanamide-κN)lithium]-μ3-bromido].

Project description:The title complex, [LiBr(C3H6N2)] n , is the unexpected product of a reaction beteween (Dipp)N(Li)SiMe3 (Dipp = 2,6-diiso-propyl-phen-yl), Me2NCN and CuBr. The compound is a one-dimensional polymer with a step structure derived from the association of inversion dimers, formed by bromido ligands bridging two Li(+) cations, each of which carries a di-methyl-cyanamide ligand. The planar (LiBr)2 unit of the polymer core has a regular rhombic shape [Li-Br-Li 77.55 (16)° and Br-Li-Br 102.45 (16)°]. These (LiBr·NCNMe2)2 dimers represent the repeat unit of a polymer system propagated by additional Br-Li and Li-Br bonds generating an infinite step structure along the a-axis direction.

catena-Poly[2-methyl-pyridinium [tungstate-di-?-selenido-silver-di-?-selenido] 2-methyl-pyridine monosolvate].

Project description:The title compound, {(C6H8N)[AgWSe4]·C6H7N} n , consists of anionic [WAgSe4] n chains, 2-methyl-pyridinium cations and neutral 2-methyl-pyridine mol-ecules. The Se atoms bridge the Ag and W atoms, forming a polymeric chain extending along the b-axis direction. Both the Ag and W atoms are located on a twofold rotation axis and each metal atom is coordinated by four Se atoms in distorted tetra-hedral geometry. In the crystal, the 2-methyl-pyridinium cation and 2-methyl-pyridine mol-ecule are linked via N-H?N hydrogen bonding. Weak C-H?Se inter-actions link the organic components and polymeric anions into a three-dimensional architecture.

Project description:The title compound, [CuBr(C(9)H(9)N(5))](n), prepared by the solvothermal treatment of CuBr with 4-(2-allyl-2H-tetra-zol-5-yl)pyridine, is a new homometallic Cu(I)-olefin coordination polymer in which dinuclear Cu(2)Br(2) units are linked by the organic olefin ligand 4-(2-allyl-2H-tetra-zol-5-yl)pyridine, which acts as a bidentate ligand connecting two neighbouring Cu(2)Br(2) units through the pyridine N atom and the double bond of the allyl group. The coordination of Cu(I) is slightly distorted tetrahedral.

Project description:The title complex, [Cu(2)Br(3)(C(11)H(9)N(2)O(2))](n), was one of three isolated by slow evaporation of an acetonitrile reaction mixture of CuBr(2) with di-2-pyridyl ketone (1:1 molar ratio).

The dimeric units are further linked by bromide ions, leading to a two-dimensional extended bridged structure. O-H?O hydrogen bonds are present in the crystal structure.
