(a) Crystal-structure fragments of DL-serinium maleate, (II)

. The C₂²(12) chains are formed by the –NH₃⁺ and –COOH groups of the serinium cations interacting with the –COO⁻ and –COOH groups of the semi-maleate anions. (b) The C₂²(12) chains are not connected directly to each other by hydrogen bonds. The C₂²(12)′ chains are formed by the –NH₃⁺ and –OH groups of the serinium cations with the –COO⁻ and –COOH groups of the semi-maleate anions. Hydrogen bonds are shown as pale dashed lines.
