New bispyridyl ligands N,N‘-bis(3-pyridylmethyl)-diphthalic diimide (L) and N,N‘-bis(3-pyridylmethyl)-oxydiphthalic diimide (L) were synthesized. Their coordination polymers [Cd(L1)1.5(NO3)2]n·nCHCl3 (1) and [Cd(L2)2(NO3)2]n·nEtOH (2) have either a 2D (6,3) brick-wall network with L1 in both Zt- and Ut-modes or a 1D chain of layered double-bridging Cd2L22 units with solely angular L2. The connection of the diimide moieties supplemented by the rich hydrogen bonding prevents interpenetration in 3D networks.
