Abstract

The crystal and molecular of N⁴-aminocytosine was determined by X-ray diffraction. This compound belongs to the monoclinic space group P2₁/a with four molecules in a unit cell of α=7.950 (2) Å ; b=11.156 (2) Å ; c=6.054 (3) Å ; β=94.59 (2)° ; V=535.2 (3) ų. The final R value was 0.072 including hydrogen atoms. The present study established that this compound takes the C (4)-amino form rather than the imino form, and is consistent with the report (D. M. Brown, M. J. E. Hewlins and P. Schell, J. Chem. Soc. (C), 1968, 1925 that 1-methyl-N⁴-aminocytosine takes the amino form in solution.
