Controllable preparation of Zn(II) coordination polymers: unusual solvothermal formation of a LiGe-type framework directed by in situ S-S coupling of 5-(4-pyridyl)-1H-1,2,4-triazole-3-thiol.
Controlled assembly of Zn(II) with a versatile ligand 5-(4-pyridyl)-1H-1,2,4-triazole-3-thiol (Hptt) in conventional or solvothermal condition affords two distinct coordination frameworks, in which the former shows a unique 3-D pseudo-polyrotaxane architecture with 1-D water tapes penetrating the 2-D Zn-ptt layers, whereas the later is generated from in situ S-S coupling of Hptt and has a very rare 2-fold interpenetrating LiGe (lig) topology.
