| Abstract: | C12H12N2O6 crystallized from methanol in the monoclinic space group P21/c (Z=4) witha=13.333(4),b=10.154(3),c=9.597(2) Å and =102.37(2)°.M
r=280.24,V=1269.1(6) Å3,D
x=1.466 g cm–3, (Mo K )=0.71069 Å, =1.29 cm–1,T=295 K. The structure was solved by direct methods and refined by full-matrix least-squares to a finalR (R
w)=0.049 (0.057) for 916 observed reflections. The molecules are linked by strong N-H O(4) hydrogen bonds with NO distance of 2.995(4) Å. The infinite racemic chains run in 001] direction. |
