Crystal and Molecular Structure of 4-Hydroxy-3-Methoxy-4-N-Methylstilbazonium Iodide C15H16NO2+·I-

The crystal structure of the title compound C15H16NO2+ · I-(Mr=369. 19) has been determined by single crystal X-ray diffraction analysis. The crystal belongs to tbe monoclinic system with space group P21/c, a=8. 957(1), b=21. 8117(2), c=7. 8760(10)A , β=103.94(1)°, V=1493.8(3)A3, Z=4, Dc=1. 642g cm3,μ=2. 141mm-1, F(000)=728, final R=0. 0264, and Rw=0. 0644(I＞2σ(I)) for 2938 independent reflections. The results show that in the crystal structure of the title compound the planar cations have two configurations, and these cations are anti-parallelly packed through the strong π…π interaction.
