摘要：

Two scandium coordination polymers, a 2D supermolecule structure {[Sc(OH)(L¹)2(H2O)]}n (1) (HL¹ = isonicotinic acid), a 1D infinite chain structure {[Sc3(L²)4(H2O)4]?·NO3?·H2O}n (2) (H2L² = 4,5-imidazole dicarboxylic acid), as well as a scandium complex {[Sc2(OH)2(L³)2(H2O)4]}n (3) (H2L³ = 1,2,3-triazole-4,5-dicarboxylic acid), were synthesized and characterized by X-ray crystallography. Compounds 1-3 are active heterogeneous catalysts for high-yield cyanosilylation of aromatic aldehydes in acetonitrile, particularly for p-nitrobenzaldehyde. Moreover, these three catalysts can be reused three times without significant loss in activity or mass.
