Novel Synthesis and Structure of a Bridging Peroxo Pentaaminecobalt(III) Dimer

Abstract

The addition of excess glycine ethyl ester to Co{(H₂NCH₂CH₂)₃N}(OSMe₂)₂³⁺ in Me₂SO leads to the symmetrical dimeric peroxo ion p,p - [Co( tren )(NH₂CH₂CO₂Et)]₂O₂⁴⁺ under mild conditions. The single-crystal X- ray structure of the perchlorate salt is described, and the mechanism for the dimer formation is considered.
