4-amino-3-methyl-6-phenyl-1,2,4-triazin-5(4H)-one (metamitron) and 4-amino-6-methyl-3-phenyl-1,2,4-triazin-5(4H)-one (isometamitron)

Abstract

The title structures, both C10H10N4O, are substitutional isomers. The N-N bond lengths are longer and the C=N bond lengths are shorter by ca 0.025 angstrom than the respective average values in the C=N - N=C group of asymmetric triazines; the assessed re
