Two Cu/Zn complexes [Cu(4,4'-bipy)(H 2 O) 2 (ClO 4 ) 2 ]n n (4,4'-bipy) ( 1 ) and [Zn(4,4'-bipy)(H 2 O) 4 ] 3n6 n (4,4'-bipy)6 n (ClO 4 )·2 n H 2 O ( 2 ) (4,4'-bipy = 4,4'-bipyridine) have been prepared via hydrothermal reactions and characterized by single-crystal X-ray diffraction. Both complexes feature an infinite 1-D chain-like structural motif with the metal ions surrounded by two nitrogen atoms and four oxygen atoms to yield a octahedral configuration. Both complexes have a 3-D coordination polymer network formed by the rich hydrogen-bonding interactions. Powder photoluminescence studies reveal that they have an emission in the blue ( 1 ) or red ( 2 ) region of the light spectrum. Time-dependent density functional theory investigation discover that the nature of the emission is resulted from the ligand-to-metal charge transfer for  1 , as well as ligand-to-ligand charge transfer for  2 . Narrow optical band gaps of 1.43 eV ( 1 ) and 2.24 eV ( 2 ) are found by the solid-state UV/vis diffuse reflectance spectra.
