Hot article details the preparation of a new pentanuclear heterotrimetallic complex [Cu2CoNi2(Me2Ea)6Cl4] with an unusual heterotrimetallic structure, like that of a butterfly.
This work is part of the authors investigation into the coordination chemistry of complexes containg copper, cobalt and nickel.
