Abstract
The reaction of a metallo-organic ligand (LA) in which two “V”-shaped bisterpyridines attaching to meta-position of “X”-shaped tetraterpyridine via <tpy-Ru2+-tpy > connectivity and Zn2+ ions gave rise to 3D supramolecular architectures: octagram (Zn8LA4). However, a position varied ligand (LB) in which two “V”-shaped bisterpyridines locating at the ortho-position of “X”-shaped tetraterpyridine afforded a different 3D hexagram (Zn6LB3). Full characterizations included NMR (1H, 13C, 2D COSY, NOESY and DOSY), ESI-MS, TWIM-MS, TEM and AFM. The resulted structures were directly determined by the position of two “V”-shaped bisterpyridines attaching to “X”-shaped tetraterpyridine. ? 2021
