Abstract
The charge density distribution of the intermetallic compound MgCu2 is obtained by the maximum entropy method (MEM) from the synchrotron powder diffraction data. In the MEM charge density map, the overlap of electron densities was clearly observed between the neighbouring Cu atoms. This clearly shows that there is a rather strong covalent bond between Cu-Cu atoms. It is also found that the Cu-Cu bonding is along the very well known kagome net, which characterizes the Laves phase structure. At least, in the case of MgCu2, the kagomé network is the electronic network in reality rather than a geometrical concept to represent structural characteristics of Laves phase compounds.
