One new nickel coordination polymer with an unsymmetric 5-(4-pyridyl)-1,3,4-oxadiazole-2-thione: Synthesis, structure and characterization

A new neutral 2D coordination polymer, {[Ni(pot)2(H2O)2] · 6H2O}n (1) (Hpot = 5-(4-pyridyl)-1,3,4-oxadiazole-2-thione), has been prepared by reacting NiII salt with the Hpot ligand under a mixed solvents medium; 1 possesses large rectangular channels to trap water molecules. It has been characterized by IR and gas sorption property as well as TG analysis.
