Abstract
The 1,2,4-triazine ring in the title compound, C14H15N3O3, is approximately planar (r.m.s. deviation = 0.019 Å); the C atom at the 6-position deviates by 0.026 (2) Å from the mean plane whereas the C atom at the 2-position deviates by 0.166 (4) Å in the opposite direction. The triazine ring is oriented at 8.60 (13)° with respect to the phenyl ring. The imino group is hydrogen-bond donor to the exocyclic O atom at the 3-position of an adjacent molecule, the hydrogen bond generating an inversion dimer.

Comment
The compound (Scheme I) was synthesized for an evaluation of its antimicrobial activity (El-Brollosy, 2008). The 1,2,4-triazine ring of is planar (r.m.s. deviation 0.019 Å); the C atom at the 6-position deviates by 0.026 (2) Å from the mean plane whereas the C atom at the 2-position deviates from the mean plane by 0.166 (4) Å in the opposite direction (Fig. 1). The amino group is hydrogen-bond donor to the exocyclic O atom at the 3-position, the hydrogen bond generating a centrosymmetric dimer (Table 1, Fig. 2).
Experimental
The compound was synthesized by using a reported method (El-Brollosy, 2008), and was recrystallized from ethanol.
Refinement
Carbon-bound H-atoms were placed in calculated positions [C–H 0.95 to 0.98 Å, Uiso(H) 1.2 to 1.5Ueq(C)] and were included in the refinement in the riding model approximation.
The imino H-atom was located in a difference Fourier map, and was refined with a distance restraint of N–H 0.88±0.01 Å; its temperature factor was refined.
