ABSTRACT
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(2n) (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.
