摘要：
A series of complexes between 1-oxide quinolines and 7,7,8,8-tetracyanoquinodimethane has been synthesized and one of them has been analyzed by x-ray diffraction methods. Crystals of the title compound are monoclinic (C15H11NO·C12H4N4), space group P21/n, a=44.525(4), b=7.326(2), c=6.531(2) Å, β=90.23(3)°. The structure was solved by direct methods and refined by block-matrix least-squares to give R=0.047 for 1865 reflections above 2 σ(I). Molecular dimensions, interplanar distances, empirical method and IR spectra suggest a π-π* interaction with very low charge-transfer in the complex. © 1990 Plenum Publishing Corporation.
