A staggered arrangement like that of the hydrogen atoms in ethane is exhibited by the six phenol groups about each pair of silver atoms in the self‐assembled three‐dimensional coordination networks [Ag 2 (H 2 L) 3 ] n X 2 n (H 2 L= N , N ′‐bis(salicylidene)‐1,4‐diaminobutane; X − =NO 3 − or ClO 4 − ); the former is depicted (for clarity the H 2 L ligands are represented by long rods and the Ag atoms by hatched circles). These solids contain short ligand‐unsupported metal–metal bonds and display intense blue photoluminescence at room temperature.
