A new Gd(III) coordination polymer, namely [Gd(bpt)(H 2 O)(DMF)] n ·3n(H 2 O) ( 1 , H 3 bpt = biphenyl-3,4′,5-tricarboxylic acid, DMF =  N , N -dimethylformamide), has been successfully synthesized under solvothermal conditions. In the structure of 1 , the dinuclear [Gd 2 (COO) 4 ] building subunits are connected by the bpt 3− ligands into a 3D framework with (3,6)-connected flu-3,6-C2/c topology. Moreover, the catalytic performances of 1 and 1′ (desolvated sample) towards the cyanosilylation of benzaldehyde and its derivatives have been tested under mild conditions. The catalytic activity of 1′ is higher than that of compound 1 , indicating that more open metal sites in coordination polymer is beneficial to the cyanosilylation reaction. In addition, in vitro anticancer activities of compounds 1 and 1′ (desolvated sample) on four human gastric cancer cells (MGC-803, SGC-790, MKN45 and AGS) were further determined.
