Syntheses, structures and luminescence of three new supramolecular complexes containing N-P-acetamidobenzenesulfonyl-glycine acid

A new ligand, N-P-acetamidobenzenesulfonyl-glycine acid (abbreviated as abglyH(2)), and three transition metal complexes [Mn(abglyH)(2)(bipy)(H2O)(2)](n) (1), [Mn(abglyH)(2)(bipy)(2)(H2O)(2)] (2) and [Zn(abglyH)(2)(H2O)(4)] (3) (bipy=4,4'-bipyridine) have been synthesized under mild conditions and characterized by IR, elemental analysis and X-ray diffraction analysis. Compound I exhibits a I-D linear chain, which is further connected to a 3-D supramolecular network through various kinds of hydrogen bonds and p-pi stacking interactions. 2 and 3 are monomeric compounds, and 2 is assembled by intermolecular hydrogen bonds and CH...pi interactions into a 3-D supramolecular network, while 3 is extended into a 2-D supramolecular network through hydrogen bonds. Fluorescent analysis shows that 3 has an emissive maximum at 353nm in the solid state at room temperature.
