Abstract
Abstract Five complexes with 3,5-dinitrosalicylate (3,5-(NO 2 ) 2 sal) and N-donor ligand, [Cd{3,5-(NO 2 ) 2 sal}(phen)(H 2 O)] n ( 1 ), Ni{3,5-(NO 2 ) 2 sal}(phen)(H 2 O) 2 ( 2 ), [Co{3,5-(NO 2 ) 2 sal}(4,4′-bipy)(H 2 O)·(H 2 O)] n ( 3 ), [Co{3,5-(NO 2 ) 2 sal}(phen)] n ( 4 ) and [Zn{3,5-(NO 2 ) 2 sal}(phen)] n ( 5 ), have been synthesized by hydrothermal reactions and characterized by single crystal X-ray analysis, where phen = 1,10-phenanthroline and 4,4′-bipy = 4,4′-bipyridine. There are one-dimensional left- and right-handed helical chains in complexes 1 , 4 and 5 , an extended 3D structure in 2 , and a 2D rectangular grid-like network in 3 . The C–H···O hydrogen bonds lead to the formation of 3D supramolecular structures in the five title complexes. The fluorescent spectra study show that compounds 1 and 5 exhibit weak fluorescent emission in the solid state at room temperature.
