A novel polymeric complex NaCo(o-pba)(3)(H2O)(3) (o-Hpba = 2-(1-oxo-1H-2,3-dihydroisoindol-2-yl)benzonic acid) based on racemic N-arylphthalimidine ligand has been prepared and characterized by elemental analysis, spectroscopic and X-ray crystallography methods. In the compound, each Co(II) cation is coordinated by six O atoms from three carboxyl groups of o-pba(-) and three water molecules in fac-MA(3)B(3) model forming a chiral tripodal Co(o-pba)(3)(H2O)(3)(-) anion-complex, enantiomeric pairs of which are alternately arranged in head-to-head and tail-to-tail orientations giving rise to a meso-one-dimensional chain-like structure. The compound exhibits high stability and unusual triple-peak luminescence in DMSO solution at room temperature.
