Abstract

The synthesis and single-crystal x-ray structure determination of two new trinuclear metal complexes is detailed. In these we utilise the appended iminodiacetate substituents, in [Co(CH3)NH(CH2CO2H)2sar]3+, to act as a focus for coordination of other metal ions. Thus, we have made complexes of Cu and Ni utilising the basic carbonates of these metals and [Co(CH3){N(CH2CO2H)2}sar]3+ (CoL2) which gave rise to ((CoL2–2H+)2M), M = Cu and Ni. The electrochemical study of the latter was inconclusive and provides the impetus for further study.

We dedicate this paper to the celebration of the scientific career of Jack McBean Harrowfield and his 65th birthday. He has been a constant source of inspiration to all of us in terms of his science and his humanity. He is ever ready to offer insights into diverse areas of chemistry, challenge us (we’ll work out what a bond is one-day!) and entertain us. Equally adept in conversation about vin and fromage as he is about his great love, kinetics. To a friend, mentor, great chemist and thrillseeker!
