Abstract Solvothermal reaction of zinc(II) and copper(II) salts with 3,3 -dipropoxy-[1,1 : 4 , 1 -terphenyl]-4,4 -dicarboxylic acid (H2L) gave rise to the 1D and 2D metal-organic frameworks (MOFs) [Zn(L)(dmf)(2)](n) (1), [Zn-2(L)(NO3)(2)(4,4 -bipyridine)(2)](n) n(DMF) (2), [Cu(L)(H2O)(2)] n center dot 2n(H2O) (3), and [Cu-3(OH)(2)(L) 2](n)center dot n(H2O) (4), which were characterized by elemental analysis, FTIR spectroscopy, and X-ray single-crystal diffraction. MOFs 1 and 3 have zigzag- and linear-type 1D structures, respectively, whereas 2 and 4 possess rectangular grid-and layer-type 2D structures. In 2 and in 4, a dinuclear ZnII cluster (C2O4Zn2) and a trinuclear mu(3)-hydroxo-bridged CuII cluster [Cu-3(OH)(2)] n, respectively, act as building block units. These frameworks act as heterogeneous catalysts (the Zn-MOFs are more active than CuMOFs, and 1 is the most efficient) for the cyanosilylation of aldehydes with trimethylsilyl cyanide at room temperature. These MOF-based heterogeneous catalysts can be easily recovered and reused, at least over a few consecutive cycles, without losing activity.
