A new cobalt(II) complex, [CoII(phen){3,5-(NO2) 2sal2-}]n (1) (3,5-(NO2) 2sal2- = 3,5-dinitrosalicylate anion, phen = 1,10-phenanthroline), the first cobalt(II) complex with 1,10-phenanthroline and 3,5-dinitrosalicylate acid ligands, has been prepared by hydrothermal synthesis and characterized by single crystal X-ray analysis, IR, XPS spectra, TG-DTA analysis and elemental analysis. This compound displays a linear one-dimensional (1D) chain though cobalt atoms and bridging carboxylate groups of 3,5-dinitrosalicylic acid ligands with Co?Co distance of 4.085 ?. Magnetic susceptibility measurements show weak antiferromagnetic interactions in the complexes.

Five complexes with 3,5-dinitrosalicylate (3,5-(NO2)2sal) and N-donor ligand, [Cd{3,5-(NO2)2sal}(phen)(H2O)]n (1), Ni{3,5-(NO2)2sal}(phen)(H2O)2 (2), [Co{3,5-(NO2)2sal}(4,4′-bipy)(H2O)·(H2O)]n (3), [Co{3,5-(NO2)2sal}(phen)]n (4) and [Zn{3,5-(NO2)2sal}(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.
