A refinement of the crystal structure of gallium
Published/Copyright:

Abstract
Now data obtained from Weissenberg photographs of single crystals of metallic gallium have been refined by projections and generalized projections of the electron density on (100). The revised positional parameters thus obtained are y = 0.1549 ± 0.0008 and z = 0.0810 ± 0.0006. The closest neighbors of a gallium atom are one at 2.484 Å, and two each at 2.691 Å, 2.730 Å, and 2.788 Å. These distances are discussed in terms of the metallic bond theories of Pauling. It is concluded that in gallium metal each atom forms one single bond and six additional bonds of order between 0.3 and 0.5.
