Single crystals of a symmetrically substituted molecule, [Zn(C3N6H6)(H2O)0.5Cl2]⋅ (C3N6H6)(H2O)(1), have been obtained. The crystal structure of 1 shows the existence of novel layered type supramolecular structure constructed by dumbbell-shape coordinated Zn moleculeand one 2,4,6-triamine-s-triazine ligand. Crystallographic data for 1: monoclinic system, space group: C2/c, a = 12.2532(9), b = 13.8606(10), c = 18.3603(13) Å, β = 99.7860(10), V = 3072.9(4) Å3 and Z = 8, Dc = 1.758 Mg/m3, R1 = 0.0518. The fluorescent property of 1 has also been studied. The luminescent property of 1 attributable to both ligand π → π* transitions and electronic transfer of ZnII→ O transitions.
