title: N1-(4-tert-Butylphenyl)-N2-hydroxy-alpha-oxo-alpha-phenylacetamidine and N2-hydroxy-N1-(4-nitrophenyl)-alpha-oxo-alpha-phenylacetamidine hemihydrate.
abstract: In the title compounds, C18H20N2O2, (I), and C14H11N3O4.0.5H2O, (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.
