| Abstract: | A new indole nitronyl nitroxide radical has been synthesized by the reaction of indole-3-aldehyde and 2,3-bis(hydroxylamino)-2,3-dimethylbutane which is the intermediate production of 2-nitropropane.Its structure was determined by single-crystal X-ray diffraction,crystallizing in orthorhombic space group P2(1)/n with a=1.111 4(7) nm,b=0.993 1(6) nm,c=1.287 7(8) nm,V=1.421 2(15) nm3,Z=4,Mr=272.32,F(000)=576,Dc=1.421 g/cm3.The largest differences in peak and hole of electron density are 173 nm-3 and-239 nm-3. |
