The title compound, [Rh(C(8)H(12))(C(18)H(36)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 ligand. The ligands form a slightly distorted square-planar coordination environment for the Rh(I) atom. An intra-molecular P-Rh-P bite angle of 83.91 (2)° is observed. The dihedral angle between the P-Rh-...

In the title mononuclear complex, [Zn(ClO(4))(C(17)H(11)N(3)O)(2)]ClO(4), the Zn(II) ion is coordinated in a distorted octa-hedral geometry. The dihedral angles between the pyridine rings and the mean planes of the 1,10-phenanthroline ring system in each of the 1-(1,10-phenanthrolin-2-yl)-2-pyridone (PP) ligands is 24.51 (10)° for the tridendate PP ligand and 73.55 (6)° for the bidentate PP lig...

Chiral ferrocene derivatives belong to privileged ligand classes for asymmetric transition metal catalysed reactions. Hetero-bidentate phosphane ligands are hybrid ligands, which combine the properties of phosphorus with those of other donor atoms. This feature creates further asymmetry around the metal centre, which may be helpful for increasing the stereoinduction. Therefore, hetero-bidentate...

A series of four novel mixed-ligand complexes of copper(II) with 3,6-dichloro-2,6-dihydroxy-1,4-benzoquinone (chloranilic acid) and 1,10-phenanthroline was prepared and characterised by X-ray structure analysis and IR spectroscopy. Three complexes exhibit square-pyramidal coordination, whereas one exhibits octahedral coordination. The ligand 1,10-phenanthroline acts in a bidentate chelating mod...

Schiff base has been prepared by the condensation of 2-naphthylamine (NA) with 5bromosalicylaldehyde (BSA). The ligand (NABSA) was isolated and characterized. Metal complexes have been synthesized by the interaction of NABSA with metal ions viz. Co(II), Ni (II), and Cu(II) in 1:2 molar ratio respectively. These complexes have been characterized by FT-IR, electronic spectroscopy, conductance mea...

In the title mononuclear salen-type complex, [Eu(NO(3))(3)(C(22)H(26)N(2)O(4))]·CH(3)OH, the Eu(III) ion is ten-coordinated by three bidentate nitrate counter-ions and one organic salen-type ligand, which acts in a bis-bidentate chelating mode through its phenolate and meth-oxy O atoms. The protonated imine groups are involved in intra-molecular N-H⋯O hydrogen bonds to the phenolate O atomss, e...

Three cis-chelating di-N-heterocyclic carbene palladium(II) complexes [Pd(X)2(di- NHC)] (X= tsac, sac and bit) tsac= thiosaccharinate, sac= saccharinate, bit= benzisothiazolinate, bearing different anionic co-ligand was synthesized characterized. A series of (2-5) homo-dicarbene ligand with varying propylene-bridged (C3) N-heterocyclic backbones (imidazole) have been by reaction [Pd(OAc)2] the ...
