1-[(Z)-2-Phenyl-hydrazin-1-yl-idene]-1-(piperidin-1-yl)propan-2-one.

ABSTRACT: A Z configuration about the imine bond [1.3025?(18)?Å] in the title compound, C(14)H(19)N(3)O, allows for the formation of an intra-moleclar N-H?N hydrogen bond between the hydrazone H and piperidine N atoms; the carbonyl group is disposed to lie over the piperidine residue, which is in a chair form. A twist between the terminal benzene ring and the hydrazine residue is seen [N-N-C-C torsion angle = 163.81?(12)°]. Helical supra-molecular chains along the c axis mediated by N-H?O hydrogen bonds are the most prominent feature of the crystal packing. The chains are connected into layers lying in the ac plane by weak C-H?? contacts involving two methyl-ene H atoms and an adjacent benzene ring.
