Ca-Pd/Pt-Ge Compounds on the Zintl Border
Zintl compounds form a category in intermetallic chemistry somewhere between metallic and ionic compounds. Classical Zintl compounds form between electropositive and electronegative elements, such as the alkaline earth metals and the p-block elements, i.e. elements with a relatively large electronegativity difference. The concept is based on the idea of a complete charge transfer from the electro
