- Abstract
- The distribution of valency electron density in Cu/sub 2/As ( /b C/38) has been determined by Fourier synthesis using as coefficients the values Delta /b F/=/b F//sub obs/-/b F/ /sub core/ (/b F//sub core/ corresponds to the structure factors of the inner orbitals). The bonding between the pyramidal-site copper atoms and the arsenic atoms is exposed, as well as the bonding between tetrahedral-site and pyramidal-site copper atoms. The structural evolution of the unit cell from the Cu/sub 2/Sb-type (/b C/38) to the Fe/sub 2/P-type (/b C/22) and Co/sub 2/P-type (/b C /23) can be related to the metal-metalloid interaction. This interaction mainly involves the pyramidal-site metal atoms in the Cu/sub 2/Sb-type, and the tetrahedral-site atoms in the Fe/sub 2 /P- and Co/sub 2/P-types.
