Micropore Formation of [Zn(Oxac) (Taz)]·(HO) via CO Adsorption.

As-synthesized [Zn(Oxac) (Taz)]·(HO), referred to as ZOTW, was prepared from aqueous methanol solutions of Zn(CO)(OH) and two kinds of ligands of 1,2,4-triazole (Taz) and oxalic acid (Oxac) at 453 K for 12 h. The crystal structure was determined by the Rietveld method. As-synthesized ZOTW was pretreated at 383 K and 1 mPa for t h, ZOTW(th).
