2-Amino-3-methyl-6-[methyl(phenyl)amino]-5-nitropyrimidin-4(3H)-one: polarized molecules within hydrogen-bonded sheets
摘要:
The pyrimidinone ring in the title compound, C12H13N5O3, is effectively planar, despite the presence of five substituents. The bond distances provide evidence for significant polarization of the electronic structure, with charge separation, and the molecules are linked into sheets by a combination of N-H center dot center dot center dot O and N-H center dot center dot center dot pi(arene) hydrogen bonds. Comparisons are made with the molecular and supramolecular structures of the precursor compound 2-amino-6-[methyl(phenyl) amino]-5-nitropyrimidin-4(3H)-one.
