| Abstract: | Three pillared polymeric complexes, {Ni2(AIP)2(4,4′-bpt)(H2O)2]·4H2O}n (1), {Co(AIP)(3,3′-bpt)]·H2O}n (2), and {Ni(AIP)(3,3′-bpt)]·H2O}n (3) (H2AIP = 5-aminoisophthalic, 4,4′-bpt = 1H-3,5–bis(4-pyridyl)-1,2,4-triazole and 3,3′-bpt = 1H-3,5-bis(3-pyridyl)-1,2,4-triazole), have been hydrothermally synthesized and characterized by X-ray diffraction analysis. Both 1 and 3 have 2-D (6,3) honeycomb layers, which are further interlinked by bent pillared triazole-bipyridine ligands to form a bilayer structure. The structures can be simpli?ed to a (3,4)- and (3,5)-connected geometrical topology, respectively. Compound 2 has a Co-AIP layer structure in which the layers are pillared by 3,3′-bpt spacers to form the 3-D CsCl net. |
