N'-Cyclododecylidenepyridine-4-carbohydrazide

A. Lemmerer, J. Bernstein and V. Kahlenberg

Abstract: The title compound, C₁₈H₂₇N₃O, is a derivative of the antituberculosis drug isoniazid (systematic name: pyridine-4-carbohydrazidei). The crystal structure consists of repeating C(4) chains along the b axis, formed by N-HO hydrogen bonds with adjacent amide functional groups that are related by a b-glide plane. The cyclododecyl ring has the same approximately `square' conformation, as seen in the parent hydrocarbon cyclododecane.
