A New Metal-Organic Framework: Product of Solvothermal Synthesis in 3D-Printed Autoclaves

A new metal-organic framework {Zn4(BDC)3(OAc)2(DMF)4} (BDC = terephthalate anion) was synthesized under solvothermal conditions in a 3D-printed polypropylene autoclave. The product was isolated in a pure state and characterized by elemental analysis and X-ray diffraction (CIF file CCDC no. 2025811). The formation of this product, instead of the expected {Zn4O(BDC)3} (MOF-5), was probably due to a change in the conditions of solvothermal synthesis caused by disruption of the integrity of the polypropylene autoclave. This is a drawback of this method of screening of metal-organic frameworks, which, however, in some cases givs rise to new representatives of this class of crystalline materials.
