The title compound, [Rh(C(8)H(12))(C(14)H(28)P(2))]BF(4), exhibits a rhodium(I) complex cation with a bidentate bis-phosphine ligand and a bidentate η(2),η(2)-coordinated cyclo-octa-1,5-diene. Together the ligands create a slightly distorted square-planar cordination environment for the Rh(I) atom. There are three mol-ecules in the asymmetric unit and intra-molecular P-Rh-P bite angles of 82.78...

In the title compound, [Cd(C(8)H(4)O(4))(C(11)H(6)N(2)O)(H(2)O)(3)]·5H(2)O, the Cd(II) atom is seven-coordinated by two N atoms from one bidentate phenanthroline-derived ligand and by five O atoms, two from one bidentate benzene-1,3-dicarboxyl-ate (1,3-BDC) ligand and three from water mol-ecules, in a distorted penta-gonal-bipyramidal geometry. Neighbouring units inter-act through π-π inter-act...

The racemic title compound, [Cu2(C7H8NO2)2Cl2], is composed of dinuclear mol-ecules in which meth-oxy(pyridin-2-yl)methano-late ligands bridge two symmetry-related Cu(II) ions. Each Cu(II) ion is coordinated in a square-planar geometry by one Cl atom, the N and O atoms of the bidentate ligand and the bridging O atom of the centrosymmetrically related bidentate ligand. The separation between the...

Neophylpalladium complexes of the type [Pd(CH(2)CMe(2)Ph)(N-O)(L)], where N-O is picolinate or a related bidentate, monoanionic ligand (6-methylpyridine-2-carboxylate, quinoline-2-carboxylate, 2-pyridylacetate or pyridine-2-sulfonate) and L is pyridine or a pyridine derivative, efficiently catalyze the oxidation of a range of aliphatic, benzylic and allylic alcohols with oxygen, without requiri...

In the title compound, [Rh(C(13)H(16)NO)(CO)(2)], a square-planar coordination geometry is observed around the Rh(I) atom, formed by the N and O atoms of the bidentate ligand and two C atoms from two carbonyl ligands. The Rh(I) atom is displaced from the plane through these surrounding atoms by 0.0085 (2) Å. The dihedral angle between the benzene ring and the N-C-C-C-O plane is 89.82 (6)°, and ...

zinc sulphate is currently used for treatment of zinc deficiency. its uptake by the body is poor, necessitating the administration of high doses. this leads to a range of unpleasant side effects. in order to increase the bioavailability of zinc, several zinc complexes have been designed and synthesized using bidentate ligands of hydroxypyranones and hydroxypyridinones. elemental analysis in eac...

Precatalyst control: [CuII(OTf)2(pyb)2]2 CH3CN (1), in which pyb is 1-(2-pyridyl)benzotriazole, enables the synthesis of a wide range propargylamines by A3 coupling reaction at room temperature absence additives. The hybrid N,N?-bidentate ligand imposes exclusive trans coordination Cu, can rotate and modulate charge distribution flux, thus orchestrating structural electronic precatalyst control...

Direct and site-selective C5 C7 palladium-catalyzed C−H arylations of 4-azaindazole N-oxide have been achieved. A bidentate ligand Pd(OAc)2 catalyst in toluene promoted the activation position, while a phosphine PdCl2 DMA directed arylation at position. Using this new method, synthesis C5, C7-diarylated N-oxides as well C3, C7-triarylated 4-azaindazoles was achieved towards future medicinal com...

In the binuclear title complex, [Dy(2)(C(7)H(3)N(2)O(6))(6)(C(12)H(8)N(2))(2)], the Dy(III) ions exhibit a distorted monocapped square-anti-prismatic geometry and are coordinated by seven O atoms of four 3,5-dinitrobenzoate (DNBA) anions and two N atoms of a phenanthroline ligand. The carboxylate groups of the DNBA anions exhibit three coordination modes: bidentate chelating, bidentate chelatin...

The title compound, [Rh(C(10)H(7)N(2)O(2))(C(18)H(15)P)(CO)]·(CH(3))(2)CO, is the second structural report of a metal complex formed with the O,O'-C(10)H(7)N(2)O(2) (neocupferrate) ligand. In the crystal structure, the metal centre is surrounded by one carbonyl ligand, one triphenyl-phosphine ligand and the bidentate neocupferrate ligand, forming a distorted square-planar RhCO(2)P coordination ...
