摘要: Two new three-dimensional metal–organic frameworks {[(CH3)2NH2]2[TM2(L)2]}n·x(solvent) (FJI-Y7, FJI = Fujian Institute, TM Zn; FJI-Y8, Cd) have been solvothermally prepared based on multifunctional pyridyl–tricarboxylate ligand 5-(5-carboxypyridin-3-yl)benzene-1,3-dicarboxylic acid (H3L). Single crystal X-ray analysis reveals that they possess non-interpenetrating binodal (4,4)-connected PtS-type networks with the Schlafli point symbol of {42·84}. Interestingly, both FJI-Y7 and FJI-Y8 can be used as highly efficient size-selective heterogeneous catalysts for solvent-free cyanosilylation acetaldehydes under mild conditions.
