摘要:
The ligand benzene-1,3,5-triyltriisonicotinate (1) was shown to form topological equivalent organic and metal organic networks upon treatment with trimesic acid (H(3)TMA) and Ag(I) salt, respectively. Both exhibit interpenetrated (10,3)-b networks, signifying the tecton equivalency between Ag(I) and H(3)TMA. The metal organic network is doubly interpenetrated, while the organic network is 8-fold interpenetrated which highlights the size differences between Ag(I) and H(3)TMA. Despite interpenetration, both the networks were found to incorporate solvents MeOH and CHCl3 in their channels. Further, the repeat of reaction of Ag(I) with 1 in the presence of a pyrene guest was found to produce crystals of open honeycomb (6,3) network with inclusion of pyrene molecules in the channels.
