Synthesis, characterization, crystal structures and photophysical properties of copper(I) complexes containing 1,1?-bis(diphenylphosphino) ferrocene (B-dppf) in doubly-bridged mode
Five copper(I) complexes having general formula [Cu2(mu-X) 2(kappa2-P,P-B-dppf)2] (X = Cl(1), Br(2), I(3), CN(4), and SCN(5)) were prepared starting with CuX and B-dppf in 1:1 molar ratio in DCM-MeOH (50:50 V/V) at room temperature. The complexes have been characterized by elemental analyses, IR, 1H NMR, 31P NMR and electronic spectral studies. Molecular structures for 1, 2 and 4 were determined crystallographically. Complexes 1, 2 and 4 exist as centrosymmetric dimers in which the two copper atoms are bonded to two bridging B-dppf ligands and two bridging (pseudo-)halide groups in a mu-eta1 bonding mode to generate nearly planar Cu2(mu-eta1-X)2 framework. Both bridging B-dppf ligands are arranged in antiperiplanar staggered conformation in 1 and 2 (mean value 56.40-56.76), and twisted from the eclipsed conformation (mean value 78.19) in 4. The Phi angle value in 4 is relatively larger as compared to 1 and 2. This seems to indicate that the molecular core [Cu2(mu-eta1-X)2] in 4 is a sterically demanding system that forces the B-dppf ligand to adopt a relatively strained conformation in comparison to less strained system in 1 and 2. All the complexes exhibit moderately strong luminescence properties in the solution state at ambient temperature.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 1111-67-7 is helpful to your research. Reference of 1111-67-7
