Crystal structures and luminescence of two cadmium(II) polymers constructed from aromatic polycarboxylate and bis(1,2,4-triazol-1-yl)methane ligands
Abstract:Two new coordination compounds, {[Cd2(btrm)(ip)2(H2O)2]?·?2H2O} n (1) and {[Cd2(btrm)(hip)2(H2O)4]?·?3H2O} n (2) (btrm?=?bis(1,2,4-triazol-1-yl)methane, H2ip?=?isophthalic acid, H2hip?=?5-hydroxy isophthalic acid), have been synthesized and structurally characterized. Compound 1 is a 3-D network with CdSO4 topology. Compound 2 contains 1-D ladder structures, which are interconnected by classical hydrogen-bonding interactions (O–H?···?O) to lead to 3-D supramolecular architectures. Luminescence was performed on 1 and 2, both of which showed strong fluorescent emissions in the solid state at room temperature.
Keywords:H2hip  H2ip  Bis(1,2,4-triazol-1-yl)methane  Fluorescence
