Abstract
The structure of a crystal with the composition CrB ∼41 has been investigated using single-crystal diffractometry. The composition represents the maximum solubility of chromium in β-rhombohedral boron. The space group is R 3m and the hexagonal axes are a = 10.964 Å and c = 23.848 Å. The three-dimensional boron network is essentially equivalent to that in β-rhombohedral boron. The chromium atoms occupy two crystallographic positions, both of which are only partially occupied. The two chromium atoms coordinate twelve and fourteen boron atoms respectively. The result of an investigation of holes in the β-rhombohedral structure is reported. There are at least eight crystallographic positions, which represent holes of sufficient size to accommodate boron or metal atoms in the structure.
