| C8H12N2O2, M(r) = 169.2, monoclinic, P2(1), a = 5.082 (1), b = 11.719 (1), c = 7.224 (1) angstrom, beta = 107.97 (5)-degrees, V = 409.2 (3) angstrom3, Z = 2, D(x) = 1.37 Mg m-3, lambda(Mo K-alpha) = 0.71073 angstrom, mu = 0.093 mm-1, F(000) = 180, room temperature, R = 0.054, wR = 0.066 for 1030 reflections (F2 > 3-sigma) out of 1544 measurements. The pyrimidine ring is planar within 0.009 (3) angstrom, and almost perpendicular to the adjacent C-C bond [torsion angle C(2)-N(1)-C(7)-C(8) = -74.4 (4)-degrees]. The N-C-C-O moiety has the sc conformation [torsion angle - 61.4 (4)-degrees]. The molecules do not for-m dimers, but infinite zigzag chains along the b axis through hydrogen bonds OH ... N(3'). Since it is not an acceptor to an H bond, the C(2)=O(2) length is 1.225 (5) angstrom. |
