文摘

New bispyridyl ligands N,N'-bis(3-pyridylmethyl)-diphthalic diimide (L¹) and N,N'-bis(3-pyridylmethyl)-oxydiphthalic diimide (L²) 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 Z_t- and U_t-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 hydrogenbonding prevents interpenetration in 3D networks.
