Abstract
In this work, two dicarboxylate ligands, 4,4′-oxybis(benzoic acid) (H2oba) and 4,4′-biphenyldicarboxylic acid (H2bpdc) were employed as coligands to perform a comparison on the structures of Cd(II)-btmx complexes (btmx = 1,4-bis(1,2,4-triazol-1-ylmethyl)-2,3,5,6-tetramethylbenzene) motifs. Two new complexes, {[Cd(btmx)(oba)]·H2O}n (1) and [Cd(btmx)(bpdc)]n (2), have been synthesized and characterized. Structural analyses show that 1 shows a 1D double-chain, while 2 displays an undulating 2D 44-sql network with 2-fold interpenetration. The structural differences of the two complexes suggest that the dicarboxylate ligands have great impact on the formation of such coordination architectures. Furthermore, the photoluminescence properties of 1 and 2 have also been investigated.
