WebThe crystal structure of Ga is too complex for one to attempt to `derive' it theoretically in any meaningful sense. However, one can test that the observed structure `makes sense' from various points of view. We find that it does, as regards number of near neighbours, their distances, covalency and the axial ratios which make Ga pseudohexagonal ...
