Crystal structure of monomethylammonium nitrate
Tóm tắt
The crystal and molecular structure of the title compound is reported. The crystals are orthorhombic:Pcmn, Z=4,a=6.414 (4),b=6.581 (4),c=10.412 (3) Å. The structure was solved by direct methods, and refined by full-matrix least squares toR=0.048 andR
w
=0.044 for 296 unique reflections. Hydrogen bonds exist between the cations and anions. Differential scanning calorimetry and vibrational studies indicate phase changes at 355 and 245 K.
