Equiatomic AEAuX (AE=Ca−Ba, X=Al−In) Intermetallics: A Systematic Study of their Electronic Structure and Spectroscopic Properties

The three intermetallic compounds SrAuGa, BaAuAl and BaAuGa were synthesised from the elements in niobium ampoules. The Sr compound crystallises in the orthorhombic KHg2‐type structure (Imma, a=465.6(1), b=771.8(2), c=792.6(2) pm, wR2=0.0740, 324 F2 values, 13 variables), whereas the Ba compounds we...
