Structural and functional evolution of metallacrowns.

Preparation of [Cu(NN)(PP)]+ derivatives has been systematically investigated starting from two libraries of phenanthroline (NN) derivatives and bis-phosphine (PP) ligands, namely, (A) 1,10-phenanthroline (phen), neocuproine (2,9-dimethyl-1,10-phenanthroline, dmp), bathophenanthroline (4,7-diphenyl-1,10-phenanthroline, Bphen), 2,9-diphenethyl-1,10-phenanthroline (dpep), and 2,9-diphenyl-1,10-phenanthroline (dpp); (B) bis(diphenylphosphino)methane (dppm), 1,2-bis(diphenylphosphino)ethane (dppe), 1,3-bis(diphenylphosphino)propane (dppp), 1,2-bis(diphenylphosphino)benzene (dppb), 1,1′-bis(diphenylphosphino)ferrocene (dppFc), and bis[(2-diphenylphosphino)phenyl] ether (POP). Whatever the bis-phosphine ligand, stable heteroleptic [Cu(NN)(PP)]+ complexes are obtained from the 2,9-unsubstituted-1,10-phenanthroline ligands (phen and Bphen). By contrast, heteroleptic complexes obtained from dmp and dpep are stable in the solid state, but a dynamic ligand exchange reaction is systematically observed in solution, an...

Synthesis, spectral and magnetic studies of mono- and bi-nuclear metal complexes of a new bis(tridentate NO2) Schiff base ligand derived from 4,6-diacetylresorcinol and ethanolamine.

Synthesis and reactivity of the copper(I) complex containing bis(diphenylphosphino)methane bridging ligands — structure of [Cu4(μ4-S)(dppm)4](PF6)2·CH2Cl2

Six new complexes of the light Ianthanide elements La, Ce, Pr, Nd, Sm and Eu with Schiff base ligands derived from salicylaldehyde and glycine have been synthesized and characterized by elemental analyses, molar electrical conductivities, magnetic moments, infrared and electronic spectra, and thermogravimetric analyses. All of the complexes were found to be non-electrolytes of the general empirical formula Ln(L)(HL)nH2O, where H2L is the glycine Schiff base ligand and n is 3 or 3. 5.

Synthesis and Characterization of Glycine Schiff Base Complexes of the Light Lanthanide Elements

The novel trinuclear CuI complex [Cu3(dppm)3(NO3)(OH)](NO3) obtained by reacting dppm with Cu(NO3)2 · 3H2O in the presence of NaBPh4 was characterized by a single-crystal X-ray analysis as well as by physico-chemical and spectroscopic methods. The [Cu3(dppm)3(NO3)(OH)]+ cation consists of a triangular array of copper atoms, (with dppm ligands bridging each edge of the triangle), a triply bridging OH group and NO−3 anion bound to two faces of the Cu3 unit, respectively.
