The complete mol-ecule of the title compound, [Zn(C(4)H(8)NS(2))(2)(C(10)H(8)N(2))], is generated by crystallographic twofold symmetry, with the Zn atom lying on the rotation axis; the axis also bis-ects the central C-C bond of the 2,2'-bipyridine mol-ecule. The metal atom is chelated by two S,S'-bidentate dithio-carbamate anions and the N,N'-bidentate heterocycle, resulting in a distorted cis-...

The asymmetric unit of the title compound, [ZnCl(2)(C(12)H(12)N(2))], contains two independent mol-ecules. The Zn(II) atoms are four-coordinated in distorted tetra-hedral configurations by two N atoms from 5,5'-dimethyl-2,2'-bipyridine and two terminal Cl atoms. In the crystal structure, inter-molecular C-H⋯Cl hydrogen bonds link the mol-ecules. There are C-H⋯π contacts between the methyl group...

Dye-sensitized solar cells based on nanocrystalline TiO(2) have been fabricated with an amphiphilic ruthenium sensitizer NaRu(4-carboxylic acid-4'-carboxylate)(4,4'-dinonyl-2,2'-bipyridine)(NCS)2, coded as Z-907Na, and a series of non-volatile 3-methoxyproprionitrile (MPN)-based electrolytes with different concentration of 1-methyl-3-propylimidazolium iodide (PMII). The short-circuit photocurre...

In the title complex, [Cu(C(2)H(3)O(2))(C(10)H(8)N(2))(2)](CH(3)CH(2)OSO(3))(0.5)(CH(3)OSO(3))(0.5), the Cu(II) ion is bis-chelated by two 2,2'-bipyridine lignds and coordinated by an O atom of an acetate ligand in a CuN(4)O disorted square-pyramidal environment. In the structure, equal amounts of methyl sulfate and ethyl sulfate anions are disordered on the same crystallographic sites. The cry...

We report on the synthesis, and photovoltaic performances of four novel Ru(ii)-bipyridine heteroleptic complexes TT206-209, incorporating branched and bulkier alkyl chains compared to their linear analogues C106 and CYC-B11 previously reported. In both series, we found that dyes containing 2-methyl-hex-2-yl substitution gave better performances than 1,1-dipropylbutyl. The best overall performan...

The syntheses of five homoleptic copper(I) complexes [CuL2][PF6] are described in which L is a 4,4'-di(4-bromophenyl)-6,6'-dialkyl-2,2'-bipyridine ligand (compounds 1-4 with methyl, (n)butyl, (iso)butyl and hexyl substituents, respectively) or 4,4'-di(4-bromophenyl)-6,6'-diphenyl-2,2'-bipyridine (5). The new ligands 2-5 and copper(I) complexes [CuL2][PF6] (L = 1-5) have been fully characterized...

In the title complex mol-ecule, [CdBr(2)(C(10)H(8)N(2))(2)], the Cd(II) ion is six-coordinated by two cis-arranged bromide anions and four N atoms of two bidentate 2,2'-bipyridine ligands in a distorted octa-hedral geometry. The dihedral angle formed by the mean planes through the bipyridine ligands is 87.01 (11)°. In the crystal packing, π-π stacking inter-actions [centroid-centroid distances ...

In the crystal structure of the title compound, {[Cu(C(6)H(2)O(5))(C(10)H(8)N(2))(H(2)O)]·2H(2)O}(n), an infinite chain parallel to [110] is formed by the linking of Cu(H(2)O)(2,2'-bipyridine) units through a furan-2,5-dicarboxyl-ate bridge. The Cu(II) atom shows a square-pyramidal geometry, with one furan-2,5-dicarboxyl-ate O atom in the apical position. The dihedral angle between the planes o...
