Crystal Structure of Deoxy‐Vasicine Zinc Complex
Abstract
Abstract The crystal structure of deoxy‐vasicine zinc complex has been determined by X‐ray structure analysis. The compound crystallizes in the monoclinic space group P2 1 /c with cell parameters a = 9.24(4), b = 14.74(2), c = 19.84(10) Å, β = 115.6°. The structure has been solved by Patterson and successive Fourier methods and refined by full matrix least‐squares methods to an R ‐index of 0.084. The molecular structure is found to be in ionic form, with ZnCl 4 as a divalent anion and two moieties of deoxy‐vasicine (C 11 H 12 N 2 H) as independent monovalent cations. The dihedral angle between the mean planes of two cationic moieties is of the order of 50°. The crystal structure seems to be stabilized by ionic and van der Waals interactions as no hydrogen bonds have been observed.
