%X The crystal structures of the title compounds, PhCOCH=NOH (5) and Na+[MeCOC(=NO-)CO2Et],-2H2O (10), have been determined by single-crystal X-ray diffraction at 295 K and refined by least squares to R 0.051, 0.062 (815, 1199 'observed' reflections) respectively. Crystals of (5) are monoclinic, P21/n, a 14.177(6), b 5.075(4), c 11.049(6) &#506;, &#946; 112.89(3)&#176;, Z4. Crystals of (10) are tetragonal, 141/a, a 19.41(1), c 10.643(5)&#506; Z 16. In (5), within the C=NOH group, C-N is 1.263(4) and N-O is 1.375(4)&#506;; in (10) C-N is 1.318(6) and N-O is 1.321(5)&#506;. In (10), the (presumably) negative C=NO- group does not coordinate the sodium ion; the latter is bridged by water molecules, occupying four close coordination positions [2.405(4)-2.552(4)&#506;] in an interesting bridged polymeric array while the remaining two coordination positions are occupied by two ligand C=O groups [2.363(4), 2.393(4) &#506;], the ligands also bridging sodium ions.
