We report the synthesis and characterization of a 3D Cu(II) coordination polymer, [Cu3 (L1)2 (H2 O)8 ]·8H2 O (1), with the use of a glycine-based tripodal pseudopeptidic ligand (H3 L1 = N,N′,N′′ -tris(carboxymethyl)-1,3,5-benzenetricarboxamide or trimesoyl-tris-glycine). This compound presents the first example of a 12-fold interpenetrated ThSi2 (ths) net. We attempt to justify the unique topology of 1 through a systematic comparison of the synthetic parameters in all reported structures with H3 L1 and similar tripodal pseudopeptidic ligands. We additionally explore the catalytic potential of 1 in the A3 coupling reaction for the synthesis of propargylamines. The compound acts as a very good heterogeneous catalyst with yields up to 99% and loadings as low as 3 mol %.
