Structure-Compostion-Property Relationships in Complex Intermetallic PhasesGordon J. Miller, Iowa State University, DMR 1005765 (1) Discovered a Novel Series of Alkaline Earth/Au/Al (Au-Rich) Compounds containing a Hexagonal Diamond network of Gold with “cations” and Au/Al triangles occupying the voids. • Examples Include: • SrAu4Al3: M3 = Al3 • SrAu5Al2: M3 = AuAl2 • (3) Sr2Au7Al2: M3 = AuAl2 (2) Discovered a Series of Alkaline Earth/Au/Al Icosahedral Compounds that are Valence Electron precise (like valence compounds); Au:Al ratio controls symmetry. SrAu6.1Al6.4 Regular: Distorted: Au,Al icosahedra:
