The structure of the valence bands of several complex alloys was investigated using the X-ray emission spectroscopy technique. In this paper, we focus on the d-like states distributions in a series of Al-based and Mg-based alloys. It is pointed out that a substantial density of d-like states is found at or just under the Fermi level in the Al s,d and Mg s,d distributions of these complex systems. It is suggested that d-like states play a significant role in the local symmetry of the crystals and contribute to select and stabilize their structures.
