Bis{μ-1-[(2-ethyl-1H-imidazol-1-yl)meth-yl]-1H-benzotriazole}bis-(iodido-cadmium).

ABSTRACT: The dinuclear title complex, [Cd(2)I(4)(C(12)H(13)N(5))(2)], lies on a crystallographic center of inversion. The Cd(II) atom is four-coordinated by two N atoms from two 1-[(2-ethyl-1H-imidazol-1-yl)meth-yl]-1H-benzotriazole (bmei) ligands and two terminal I atoms in a distorted tetra-hedral coordination environment. The Cd(II) atoms are connected to each other by two bridging bmei ligands. The benzotriazole rings in adjacent mol-ecules are almost parallel, with an average inter-planar distance of 3.3400 (2) Å and a centroid-centroid distance of 4.852 (2) Å.

Project description:In the polymeric title complex, [CdCl(2)(C(12)H(13)N(5))](n), the Cd(II) atom is five-coordinated by two N atoms from two bridging 1-[(2-ethyl-1H-imidazol-1-yl)meth-yl]-1H-benzotriazole (bmei) ligands, two bridging Cl atoms and one terminal Cl atom in a distorted trigonal-bipyramidal geometry. The Cd(II) atoms are connected alternately by the Cl atoms and bmei ligands, leading to a zigzag chain extending parallel to [011]. π-π inter-actions, with a centroid-centroid distance of 3.3016 (3) Å, help to stabilize the crystal packing.

Bis(μ-1,2-bis-{[2-(2-pyrid-yl)-1H-imidazol-1-yl]meth-yl}benzene)bis-[bis-(thio-cyanato-κN)cadmium(II)].

Project description:The asymmetric unit of the binuclear title compound, [Cd(2)(NCS)(4)(C(24)H(20)N(6))(2)], contains one half-mol-ecule, consisting of one Cd(2+) cation, two half 1,2-bis-{[2-(2-pyrid-yl)-1H-imidazol-1-yl]meth-yl}benzene (L) ligands and two SCN(-) anions. The dimeric cyclic mol-ecule is completed by crystallographic inversion symmetry. The Cd(2+) cation is coordinated by two N atoms from two SCN(-) anions and four N atoms from two symmetry-related L ligands, exhibiting a distorted octrahedral coordination. A two-dimensional supra-molecular network stacked parallel to [210] is finally formed by linking these dimers through weak π-π stacking inter-actions between the pyridine rings and benzene rings of adjacent dimers, with a plane-to-plane distance of 3.36 (6) Å and a centroid-centroid distance of 3.67 (2) Å. One of the thio-cyanate S atoms is equally disordered over two positions.

Project description:In the title coordination polymer, [Cd(C(9)H(6)O(4))(C(12)H(10)N(4))(H(2)O)](n), the Cd(II) atom has a NO(6) donor set and is coord-inated by five carboxyl-ate O atoms from three different 5-methyl-1,3-phenyl-enediacetate (pda(2-)) anions, one O atom from a water mol-ecule and one N atom from a 1,4-bis-(1H-imidazol-4-yl)benzene (L) ligand, displaying a highly distorted penta-gonal-bipyramidal geometry. Each pda(2-) anion acts as a μ(3)-bridge, linking Cd(II) atoms to form one-dimensional slabs extending parallel to [010]. In the crystal, adjacent mol-ecules are linked through N-H⋯N and N-H⋯O hydrogen bonds into a three-dimensional network.

5,5'-Bis[(1H-imidazol-1-yl)meth-yl]-2,2'-bipyridine methanol disolvate.

Project description:The title compound, C(18)H(16)N(6)·2CH(3)OH, was prepared by the reaction of 5,5'-bis-(bromo-meth-yl)-2,2'-bipyridine with imidazole. The main mol-ecule lies on an inversion center located at the mid-point of the C-C bond joining the two pyridine rings. The asymmetric unit therefore contains one half-mol-ecule and one methanol solvent mol-ecule. The dihedral angle between the pyridine and imidazole rings is 72.32 (5)°. In the crystal, weak inter-molecular O-H⋯N, C-H⋯N and C-H⋯O hydrogen bonds contribute to the stabilization of the packing.

catena-Poly[copper(I)-bis-[?-3-(1H-imidazol-2-yl)pyridine]-copper(I)-di-?-iodido].

Project description:The title polymeric compound, [Cu(2)I(2)(C(8)H(7)N(3))(2)](n) [C(8)H(7)N(3) = 3-(1H-imidazol-2-yl)pyridine (HIPy), where HIPy comes from the in situ deca-rboxylation of 2-(pyridin-3-yl)-1H-imidazole-4,5-dicarb-oxy-lic acid (H(3)PyIDC)], was obtained under solvo-thermal conditions. Each Cu(I) cation is in a distorted tetra-hedral coordination environment defined by two iodide anions and two nitro-gen atoms from two individual HIPy ligands. Two Cu(I) atoms are connected by two HIPy ligands to form a dimer and these dimers are further bridged through the iodide atoms, leading to a chain structure extending parallel to [100]. Moreover, inter-molecular N-H?I hydrogen bonds and weak ?-? stacking inter-actions [centroid?centroid distances of 3.809?(4)?Å, an inter-planar separation of 3.345?(3)?Å and a ring slippage of 1.822?Å] between pyridyl rings link the chains into a two-dimensional supra-molecular network in the ac plane.

Poly[[(?2-benzene-1,3-di-carboxyl-ato){?2-1,4-bis-[(1H-imidazol-1-yl)meth-yl]benzene}-cadmium] di-methyl-formamide monosolvate].

Project description:The title coordination polymer, {[Cd(C8H4O4)(C14H14N4)]·C3H7NO} n , was synthesized by solvothermal reaction of metallic cadmium with the semi-rigid neutral ligand 1,4-bis-[(1H-imidazol-1-yl)meth-yl]benzene (bix) and the V-shaped benzene-1,3-di-carb-oxy-lic acid (m-H2bdc). The structure exhibits a pseudo-C-centring which is almost fulfilled by the polymeric metal complex but not by the solvent dimethylform-amide (DMF) mol-ecules. The asymmetric unit contains two independent Cd(II) ions, two m-bdc(2-) ligands, one and two half bix ligands, and two solvent DMF mol-ecules. The Cd(II) ions are both five-coordinated by three O atoms from two different m-bdc(2-) ligands and two N atoms from two different bix ligands in a distorted square-pyramidal geometry. The m-bdc(2-) ligands adopt a chelate-monodentate coordination mode, connecting neighboring Cd(II) ions into a zigzag chain parallel to [110]. Adjacent chains are further cross-linked by bix ligands, giving rise to a puckered sheet nearly perpendicular to the chain direction. Thus, each Cd(II) ion is connected to four neighboring Cd(II) ions through two m-bdc(2-) anions and two bix ligands, giving rise to the final non-inter-penetrating uninodal layer with sql (4,4) topology.
