| Abstract: | 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 × H2O}2 ( 2Pd ) 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 Zn2+ ion in {(H2O)LZn]CF3SO3 × 2 H2O}∞ ( 3Zn ) is best described as distorted trigonal‐bipyramidal. The N3O2 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 (H2O)2(anion)2 motif as for 2Pd , but whereas the former forms discrete dimers, 3Zn forms a more complicated two‐dimensional coordination polymer with additional intermolecular hydrogen bonds. |
