Abstract
Three zinc(II) carboxyphosphonates [Zn3(5-pmipe)2]·0.5H2O (1·0.5H2O), [Zn3(5-pmipm)2]·H2O (2·H2O), and [Zn3(5-pmipH)2(bpy)0.5]·6H2O (3·6H2O) (5-pmipH4=5-(phosphonomethyl)isophthalic acid, 5-pmipeH3=[C6H3(CO2H)(CO2Et)(CH2PO3H2)], 5-pmipmH3=[C6H3(CO2H)(CO2Me)(CH2PO3H2)], bpy=4,4′-bipyridine) were synthesized under hydrothermal conditions. Compounds 1 and 2 are isostructural. In compounds 1 and 2, the {ZnO4} and {CPO3} tetrahedra are interconnected into a zigzag infinite chain via corner-sharing. In addition, these chains are further linked by carboxyphosphonate ligands into a 2D layer. Interestingly, one carboxylate group experiences an in situ esterification reaction with ethanol and methanol, respectively. Compound 3 displays a 3D pillared-bilayer open framework structure. The {ZnO4}, {ZnO3N} and {CPO3} tetrahedra are interlinked through corner-sharing into one chain, which are joined together by 5-pmipH3− into a bilayer. The layers are pillared up by bpy into 3D network. The luminescent properties of compounds 1–3 were investigated in solid state at room temperature.
