C11H10N2O2 crystallizes triclinically, space group
, Z = 2; a = 8.261(1) Angstrom, b = 8.478(1) Angstrom, c = 8.470(1) Angstrom, alpha = 72.49(1)degrees, beta = 89.58(1)degrees, gamma = 67.56(1)degrees, R = 0.068 for 549 observed reflections [I greater than or equal to 2 sigma(1)]. The molecule of the title compound is nearly planar. The dihedral angle between the weighted least-squares plane through the non-Il atoms of the pyridine ring (maximum deviation from planarity 0.012(2) Angstrom) and the weighted least squares plane through the remaining non-H atoms of the molecule (maximum deviation from planarity 0.027(2) Angstrom) is 3.91(5)degrees.
