Abstract
The salt of bis(2,3,5-trimethylpyridine N-oxide) 2,4,6-trinitrophenolate, C22H25N5O9, crystallizes in monoclinic space group C2/c with a=12.411(2)Å, b=15.326(3)Å, c=13.559(3)Å, β=113.13(1)°, V=2371.8(8)Å3, Z=4, D c=1.410 mg/m3, F(000)=1056. The molecule of 2,3,5-trimethylpyridine N-oxide is protonated. Two pyridine N-oxide molecules are linked by extremely strong OHO hydrogen bonding (2.378(4)Å) to form a cation complex. CHO hydrogen bonding and π–π interactions also play important role in stablizing the structure of the salt.
