Abstract
In the title compound, C6H7N3O3, the NNO2 group is twisted ca 59 degrees fr
om the planar pyridine ring. The nitramino group is almost planar, with the
N7 atom diverging 0.15 Angstrom from the C4-N8-C11 plane. The lone pair on
N7 is included into the N-nitro group pi-electron system resulting in two
independent sets of multicenter pi-orbitals. Significant anisotropy of the
temperature dependence of thermal expansion is observed in the range 90-300
K.
