Crystallographic and geometry-optimization study on 2, 4, 6-trinitrophenol: 3-methyl-4-nitropyridine N-oxide (1/1)

In the crystal structure of 2,4,6-trinitrophenol:3-methyl-4-nitropyridine N-oxide (1/1) (TNP:POM), the hydroxyl group of TNP is hydrogen bonded to the N-oxide oxygen atom of POM [O⋯O = 2.607(5) Å], and adjacent molecules are linked by a supramolecular C-H$_{aromaric}$⋯O$_{N-oxide}$ interaction acros...
