Abstract Two Gadolinium coordination polymers {[Gd·(TTTA)·(H2O)2]·2H2O}n (1) and [Gd·(TTTA)·DMF]n (2) have been synthesized based on Gd(NO3)3·6H2O and the flexible tripodal ligand 2,2′,2″-[1,3,5-triazine-2,4,6-triyltris(thio)]tris-acetic acid (H3TTTA) under hydrothermal conditions. In the structure of 1, the tridentate TTTA3− ligands connect the dimeric metal centers into an infinite one dimensional chain. While 2 shows a two dimensional network with tridentate TTTA3− ligands. The two complexes all quench the emission spectra after coordinated to the Gd3+ ions. The catalytic results indicate that two complexes show excellent activities for the cyanosilylation of benzaldehyde and its derivatives. Besides, 2 is better than 1 in the catalytic reactions due to more possibility of metal open sites.
