Summary: | Amino acid complexes of transition metals show interesting hydrogen-bonding motifs. In this paper, the syntheses and structures of three <i>β</i>-amino acid complexes of palladium that differ only by the substitution on the <i>β</i>-carbon will be discussed. With only hydrogen on the <i>β</i>-carbon, no additional water is incorporated into the crystal lattice and hydrogen-bonding is all complex-to-complex. With the addition of one and two methyl groups on the amino acid <i>β</i>-carbon, water is incorporated into the crystal lattice giving intricate water networks held together by complex-to-water and water-to-water hydrogen-bonding networks.
