Abstract

Two pairs of isomeric copper(II) chelates of the composition Cu(dm)(NO3)2 and Cu(dp)(NO3)2, resp., have been prepared (dm=6,7-dihydro-5,8-dimethyl-dibenzo[b,j][1,10]phenanthroline), anddp=6,7-dihydro-5,8-diphenyl-dibenzo[b,j][1, 10]-phenanthroline). By ESR, IR, and visible reflectance spectra the structures of the first coordination sphere of these chelates have been established, the two Cu(dm) (NO3)2 chelates and the brown α-Cu(dp) (NO3)2, having coordination number six while the green β-Cu(dp) (NO3)2 has coordination number seven. In comparison with the diamagnetically diluted complexes (solution, powder) the isomerism is found to be typical only for undiluted copper(II) complexes.
