Fig. 3: Structural motifs of crystalline KAg2.
From: Structure and chemical bonding in high-pressure potassium silver alloys
The crystal structure is constructed from the precursor face-centered cubic (FCC) Ag. a shows interconnected Ag-tetrahedra (open circles) and K atoms (solid, purple). The Ag atoms are arranged in (b) 2-D quadrilateral (plane B) and hexagonal (Kagome) Ag planes (plane A). c shows the Ag sites replaced by K.
