Yong Fan and Jianing Xu, Jilin University, Changchun, China, and colleagues have synthesized three Sc compounds by using discrete carboxylate ligands under solvothermal conditions.
These include two Sc coordination polymers, namely a 2D supermolecule structure {[Sc(OH)(L1)2(H2O)]}n (1) (HL1 = isonicotinic acid) and a 1D infinite chain structure {[Sc3(L2)4(H2O)4]•NO3•H2O}n (2) (H2L2 = 4,5-imidazole dicarboxylic acid), as well as a Sc complex {[Sc2(OH)2(L3)2(H2O)4]}n (3) (H2L3 = 1,2,3-triazole-4,5-dicarboxylic acid).

These three new solid materials are active heterogeneous catalysts for high-yield cyanosilylation of aromatic aldehydes in acetonitrile, particularly for p-nitrobenzaldehyde. The compounds which show high chemical stability in CH3CN could be easily recovered by filtration and reused at least after three cycles without significant loss of yield. In addition, they also display intense fluorescence in the solid state at room temperature.
