N′-Cyclo-dodecyl-idene-pyridine-4-carbohydrazide

Abstract

The title compound, C18H27N3O, is a derivative of the anti-tuberculosis drug isoniazid (systematic name: pyridine-4-carbohydrazidei). The crystal structure consists of repeating C(4) chains along the b axis, formed by N-H⋯O hydrogen bonds with adjacent amide functional groups that are related by a b-glide plane. The cyclo-dodecyl ring has the same approximately square conformation, as seen in the parent hydro-carbon cyclo-dodecane.
