Abstract
The title compound, C24H26N4O4, is a diaza-crown ether encompassing linked phenylpyrazolyl and benzimidazole units that contribute five atoms to the 16-atom ring. The two planar phenylpyrazolyl and benzimidazole units are aligned at an angle of 66.4 (1)°. The carbonyl O atom of the benzimidazole unit is directed away from the middle of the ring.
