This work reports structural investigations on two metal complexes of the functionalized ( p ‐carboxylatobenzyl)‐bis(2‐picolyl)amine ligand 1 (HL). The complex {[HLPdCl]Cl × H 2 O} 2 ( 2 Pd ) has a square‐planar coordination around the Pd ion. It forms discrete dimers by intermolecular hydrogen bonding involving the protonated ligand HL. The coordination around the Zn 2+ ion in {[(H 2 O)LZn]CF 3 SO 3 × 2 H 2 O} ∞ ( 3 Zn ) is best described as distorted trigonal‐bipyramidal. The N 3 O 2 ligand sphere is composed of three nitrogen atoms from the bpa ligand, one water molecule, and a carboxylate oxygen atom from a neighbouring molecule, thus forming infinite chains along the crystallographic a axis. Further intermolecular interactions are based on the same (H 2 O) 2 (anion) 2 motif as for 2 Pd , but whereas the former forms discrete dimers, 3 Zn forms a more complicated two‐dimensional coordination polymer with additional intermolecular hydrogen bonds.
