A benzopyran derivative substituted at position 3.
In (E)-3-[[(diphenoxyphosphoryl)methylhydrazono]methyl]-4H-1-benzopyran-4-one, C(23)H(19)N(2)O(5)P, the benzopyran-methylhydrazone moiety is planar and the two phenoxy phenyl rings are inclined at angles of 21.29 (6) and 89.33 (5) degrees. Weak C[bond]H...O and C[bond]H...N intramolecular interactions exert some influence on the planarity and orientation of that moiety.
