摘 要：Open-framework microporous materials have been extensively studied during the past decades due to their rich structural chemistry and widespread potential applications in catalysis,adsorption,ion-exchange processes and so forth[1-3].Since the discovery of crystalline aluminophosphate molecular sieves in 1982,a great deal of effort has been paid to the synthesis of open-framework microporous metal *** recently,the synthesis of open-framework metal phosphites by incorporating the pseudo-pyramidal phosphite groups[HPO]in place of tetrahedral phosphate units[PO]into the frameworks has resulted in a new class of metal phosphite compounds with more open *** Bonavia et *** the first organically templatedphosphite with open framework,notable examples are *** an important class of inorganic framework materials,metal phosphites exhibit rich compositional and structural diversity,because the presence of three-connected HPOcenters favors to reduce the M-O-P connectivity to generate interrupted open-framework with low-coordinated large pore sizes and low framework *** on mentioned information,by employing three-connected HPOcenterand Co/Mncations,we successfully prepared two novel phosphites[(CH)NH]M(HPO)(M=Co(1),Mn(2))with extra-large 16-membered ring(16MR)*** Co and Mn centers are in tetrahedral sphere,forming 3D open *** one example of four-coordinate heterometals manganese phosphite(Zn/Mn)has ever been reported in a retracted article,the compound 2 is the first four-coordinate monometallic manganese phosphite.
