A hydrothermal reaction of CuCl2 center dot 2H(2)O, 4,5-diazafluoren-9-one (L) and K-3[Fe(CN)(6)], which is used as an environment friendly cyanide source, produces a two-dimensional copper cyanide complex Cu-10(CN)(10)L-4 (1). In the complex, the L ligands act as corner and bridge ligands simultaneously. With the help of the corner ligands, infinite Cu(CN)(infinity) chains are formed. The chains are further bridged by another type of L ligand forming a 2D layer with a Cu-20(CN)(18)L-2 macrocycle, which shows blue photoluminescence related to centered pi-pi* transitions of the L ligand.
