8-[(Hydrazinyl­idene)meth­yl]-4-methyl-2-oxo-2H-chromen-7-yl 4-methyl­benzene­sulfonate

Abstract

In the title compound, C(18)H(16)N(2)O(5)S, the coumarin ring system is nearly planar, with a maximum out-of-plane deviation of 0.078 (1) Å (r.m.s. deviation = 0.046 Å). The dihedral angle between the coumarin ring system and the toluene ring (r.m.s. deviation = 0.004 Å) is 2.77 (1)°. The crystal packing is stabilized by C-H⋯O and N-H⋯O inter-molecular hydrogen bonds generating C(8), C(9) and C(11) chains and R(2) (2)(14), R(2) (2)(23) and R(4) (3)(13) ring graph sets.
