چکیده
Recrystallisation of Ag[L(1)] (HL(1) = 3{5}-[pyrid-2-yl]-5{3}-tert-butylpyrazole) in the presence of halide anions leads to two polymorphs of [Ag(3)(μ-Br)(μ-L(1))(2)], which differ in their mode of supramolecular association, and the cluster [Ag(10)(μ-L(1))(8)]Cl(2). In contrast, Ag[L(2)] (HL(2) = 3{5}-[isoquinol-1-yl]-5{3}-tert-butyl-pyrazole) crystallises as a cyclic tetrameric molecule.

In the title compound, [Mn(C(19)H(11)F(2)O(2))(2)(C(5)H(8)N(2))(2)], the Mn(2+) cation is coordinated by the N atoms of two 3,5-dimethyl-pyrazole ligands and carboxyl-ate O atoms from two 4,4''-difluoro-1,1':3',1''-terphenyl-2'-carboxyl-ato ligands, forming an MnN(2)O(2) polyhedron with a slightly distorted tetra-hedral coordination geometry. Two intra-molecular hydrogen bonds are observed betw...
متن کاملChiral phosphine-phosphoramidite ligands for highly efficient Ir-catalyzed asymmetric hydrogenation of sterically hindered N-arylimines.
A mild and general iridium-catalyzed, highly enantioselective hydrogenation of sterically hindered N-arylimines with a new H(8)-BINOL-derived phosphine-phosphoramidite ligand has been developed. The present catalytic system features high turnover numbers (up to 100000) and good to perfect enantioselectivities (up to 99% ee) for the hydrogenation of a variety of sterically hindered N-arylimines.
متن کاملChemical consequences of pyrazole orientation in Ru(II) complexes of unsymmetric quinoline-pyrazole ligands.
A series of homoleptic Ru(II) complexes including the tris-bidentate complexes of a new bidentate ligand 8-(1-pyrazol)-quinoline (Q1Pz) and bidentate 8-(3-pyrazol)-quinoline (Q3PzH), as well as the bis-tridentate complex of bis(quinolinyl)-1,3-pyrazole (DQPz) was studied. Together these complexes explore the orientation of the pyrazole relative to the quinoline. By examining the complexes struc...

The synthesis, characterization and quantum-chemical investigations of two new Co(II) complexesderived from fluorescent benzimidazoles have been reported. Two new fluorescentheterocyclic ligands were synthesized from the reduction of imidazo[4',5':3,4]benzo[1,2-c]isoxazole derivatives, and characterized by elemental analyses, IR, mass, and NMR spectra. Coordination of the bidentate ligands ...
