Di-?-bromido-bis-[bromido(4,4'-dimethyl-2,2'-bipyridine-?N,N')mercury(II)].

ABSTRACT: The asymmetric unit of the title compound, [Hg(2)Br(4)(C(12)H(12)N(2))(2)], contains one half-mol-ecule. The Hg(II) atom is five-coordinated in a trigonal-bipyramidal configuration by two N atoms from the chelating 4,4'-dimethyl-2,2'-bipyridine ligand, two bridging Br and one terminal Br atom, leading to a centrosymmetric dimeric mol-ecule. There is a ?-? contact between the pyridine rings [centroid-to-centroid distance = 3.756?(5)?Å].

Project description:In the crystal of the title polymeric compound, [CdBr2(C12H12N2)] n , the Cd(II) cation is located on a twofold rotation axis and is six-coordinated in a distorted octa-hedral geometry formed by two N atoms from the 4,4'-dimethyl-2,2'-bipyridine ligand and by four bridging Br(-) anions. The bridging function of the Br(-) anions leads to a polymeric chain running along the c axis. Weak C-H?? inter-actions observed between adjacent chains are effective in the stabilization of the three-dimensional packing.

Project description:In the title compound, [Cu(3)(CN)(3)(C(12)H(12)N(2))(2)], two 2,2'-bipyridine N,N'-chelated Cu(I) atoms are linked by a cyanide bridge that lies about a center of inversion; the Cu(I) atom exists in a tetra-hedral coordination geometry. This dinuclear entity is linked to another Cu(I) atom that lies on a twofold rotation axis by another cyanide bridge, these bridges giving rise to the formation of a linear chain motif.

Di-μ(2)-chlorido-bis-[aqua-(2,2'-bipyridine-4,4'-dicarboxylic acid-κN,N')(nitrato-κO)copper(II)].

Project description:In the title compound, [Cu(2)Cl(2)(NO(3))(2)(C(12)H(8)N(2)O(4))(2)(H(2)O)(2)], which consists of a chloride-bridged Cu(II) dimer, the Cu atom is in a distorted octa-hedral environment defined by two N atoms from the 2,2'-bipyridine-4,4'-dicarboxylic acid ligand (H(2)bpdca), two bridging chlorido ligands, and two O atoms from an equatorial water mol-ecule and an axial nitrate anion, respectively. The two halves of the dimeric unit are related by an inversion centre at the midpoint between the two Cu atoms. Both carboxylic acid groups in the H(2)bpdca ligand remain protonated, as confirmed by the two sets of C-O bond lengths. The dinuclear mol-ecules are linked into a three-dimensional network via inter-molecular hydrogen bonds.

Project description:The title dimethyl-tin diisothio-cyanate adduct of 4,4'-bipyridine, [Sn(CH(3))(2)(NCS)(2)(C(10)H(8)N(2))](n), adopts a chain motif in which the N-heterocycle functions as a bridge to adjacent all-trans octa-hedrally coordinated tin atoms. The Sn(IV) atom lies on a special position of 2/m site symmetry, the methyl C atom on a special position of 2 site symmetry, and the thio-cyanate and 4,4'-bipyridine on a special position of m site symmetry.

catena-Poly[[(2,2'-bipyrimidine-κN,N)diperchloratocopper(II)]-μ-4,4'-bipyridine-κN:N'].

Project description:The central CuN(4)O(2) motif of the title compound, [Cu(ClO(4))(2)(C(8)H(6)N(4))(C(10)H(8)N(2))](n), exhibits a Jahn-Teller-distorted octa-hedral geometry around the metal centre, showing a considerably long Cu-O bond distance of 2.634 (4) Å towards the second perchlorate group occupying the sixth coordination site, giving a (4+1+1)-type coordination mode. The 4,4'-bipyridine (bipy) ligands are highly twisted with respect to each other, the dihedral angle between the two pyridyl ring planes being 38.9 (2)°. The bipy ligands act as bridging ligands between [Cu(ClO(4))(2)(2,2'-bpym)] (2,2'-bpym is 2,2'-bipyrimidine) units, generating an infinite one-dimensional zigzag chain along [010]. Intra- and intermolecular C-H⋯O hydrogen bonds are present in the crystal structure.
