  • adj. clinging tightly.

    "Malcolm Green developed Metal Vapour Synthesis (invented originally by Peter Timms) as a technique, isolating a huge range of unusual compounds of extreme electron richness and reactivity. He and his students designed and synthesised striking examples of metal-alkyl compounds containing metal-hydrogen-carbon bonds which he named agostic bonds.The word was suggested to him by Jasper Griffin, professor of Classics at Balliol College, Oxford, whom Green asked for an appropriate Greek word to describe the close bonding phenomenon. "Agostos" is an obscure word in Homer which seems to mean clinging tightly."
