Many intermolecular complexes between <I>N</I>-acylamino acids and nucleotide bases have been found by means of X-ray powder diffractometry. Among these, the crystal structure of <I>N</I>-benzoylglycine cytosine complex monohydrate has been determined by the direct method. The crystal data are: <I>a</I>=18.71,<I>b</I>=7.11,<I>c</I>=18.37 Å, and β=144.0°. The space group is <I>P</I>2<SUB>1</SUB>⁄<I>c</I>; <I>D</I><SUB>obsd</SUB>=1.37; <I>D</I><SUB>calcd</SUB>=1.35 g/cm<SUP>3</SUP>. The final <I>R</I> factor was 0.131. In the crystal, a cytosinyl cation and a <I>N</I>-benzoylglycyl anion are joined by two NH···O hydrogen bonds, of which the shorter one is 2.652 Å long. Such a complex formation may exist <I>in vivo</I>.
