Abstract: Two novel cadmium(II) coordination polymers, [Cd2-(bpda) 2(dpe)]n (1) and [Cd2[(R)-Hdmpa} 2{(S)-Hdmpa}2-(dpe)3]n (2), [H 2bpda = 1,1′-biphenyl-3,3′-dicarboxylic acid, H 2dmpa = 6,6′-dimethyl-1,1′-biphenyl-2,2′ -dicarboxylic acid, and dpe = 1,2-di(4-pyridyl)ethylenel have been prepared by hydrothermal reactions of both Cd(NO3)2·4H 2O and dpe with H2bpda and H2dmpa, respectively. 1 is a threefold interpenetrating three-dimensional coordination network composed of paddle-wheel tetracarboxylate dicadmium(II) units bridged by dpe. 2 affords an example of ligand self-discrimination in an assembly process, in which dpe connects the [Cd{(R)-Hdmpa]{(S)-Hdmpa}] building units to generate a one-dimensional ladder structure.
