Aluminium hydride is not an easy compound to work with, and has a very complex structure, but it also forms – and we found ways of making it – complexes. So you could add a ligand onto aluminium hydride, and one that Malcolm Wallbridge and I, with Allan Storr worked on was one molecule of ammonia onto aluminium hydride made a tetrahedral complex. You can put a second molecule on, which makes it five co-ordinate, and I think this was the first, or one of the first, five co-ordinate aluminium compounds that there were. And gallium hydride did the same. That was unusual.
Norman Greenwood (1925-2012) was born in Australia and graduated from Melbourne University before going to Cambridge. His wide-ranging research in inorganic and structural chemistry made major advances in the chemistry of boron hydrides and other main-group element compounds. He also pioneered the application of Mössbauer spectroscopy to problems in chemistry. He was a prolific writer and inspirational lecturer on chemical and educational themes, and held numerous visiting professorships throughout the world.
