N-(Acetylamino)phthalimide [monoclinic, a = 7.0228(15), b = 4.7285(8), c = 28.882(6) a<<, beta = 90.131(7)A degrees, space group P2(1)/c] shows an unusual crystal structure with marked pyramidalization at the phthalimide N and strong intermolecular NH to CO hydrogen bonding leading to the groups at the two ends of the hydrazine adopting an almost perpendicular arrangement. A survey of previous triacyl and tetraacyl hydrazine structures shows that both these features are unusual, with most examples being essentially planar at N and with torsion angles about the N-N bond of 63A degrees-82A degrees.
