Abstract. A porous MOF, [ {Zn 3 (BTC) 2 (H 2 O) 3 }·2.5H 2 O] n (H 3 BTC = 1,3,5-benzenetricarboxylic acid) was synthesized by heating ZnCl 2 and H 3 BTC in DMF at pH 8.2. A single-crystal XRD study reveals a 3D polymeric unit constructed by paddlewheel SBUs. The title MOF displays remarkable iodine uptake in both water and hexane medium (84% and

Zinc. Zinc is a lustrous bluish-white metal. It is found in group IIb of the periodic table.It is brittle and crystalline at ordinary temperatures, but it becomes ductile and malleable when heated between 110°C and 150°C. From Wikipedia, the free encyclopedia Zinc acetate is a salt with the formula Zn (CH 3 CO 2) 2, which commonly occurs as the dihydrate Zn (CH 3 CO 2) 2 ·2H 2 O. Both the hydrate and the anhydrous forms are colorless solids that are commonly used in chemical synthesis and as dietary supplements.
