Abstract

Abstract: The systhesis, characterization and molecular structure of [(dien)Cu(H₂O) (β-r,r'-bpy) Rh(NH₃)₅](ClO₄)₅.H₂Owere studied.The title compound crystallized in space group Pbca, with unit cell constants, a = 14.425(1) Å,b=29.589(2) Å,c=16.893(6) Å,a=β=r=90°,Z=8.R= 0.065.In the molecule Cu²⁺and Rh³⁺are separately in square-pyramidal and octahedral configurations, bridged by r,r'-bipyridyl.The angle of two planes of pyridines in r,r'-bipyridyl of title compound is about 51°, more than that of r,r'-bipyridyls in other compounds.From obtained ESRspectra the bond parameters of Cu²⁺ in the title compound were calculated and bonding characters of the compound were discussed.

Key words: r,r'-Bipyridyl, Rh-Cu complex, Synthesis, Molecular structure, ESR spectra
