N-1-(4-tert-butylphenyl)-N-2-hydroxy-alpha-oxo-alpha-phenylacetamidine and N-2-hydroxy-N-1-(4-nitrophenyl)-alpha-oxo-alpha-phenylacetamidine hemihydrate

Abstract

In the title compounds, C18H20N2O2, (I), and C14H11N3O4.-0.5H(2)O, (II), respectively, the oxime groups have an E configuration. In (I), the molecules exist as polymers bound by intermolecular C-H...O and O-H...N hydrogen bonds around inversion centres. In ( II), intermolecular OW-H...N, OW-H...O and O-H...OW interactions stabilize the molecular packing.
