&I EPR study of the tiis(di-i;ogropy!-dijelenophosphato)copper tion and in frozen state is reported. Superhyperfine splitting from one (47 complex, [iC3H70)2PSeSe] ECU, both in solu-Se and two 31P nuclei is observed, the Latter being isotropic.

โฆ Synopsis
The EPR spectrum of Cu(lI)-bis-(di-a-butyldiselenocarbamatc)
was measured in solution. The Cu-HFS allows an estimate of the degree of covnlcncy for the Cu-Se o-bond. It was compared with parameters for some sulphur analogous complexes.
