摘要：

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) angstrom, beta = 115.6-degrees. 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 ZnCl4 as a divalent anion and two moieties of deoxy-vasicine (C11H12N2H) as independent monovalent cations. The dihedral angle between the mean planes of two cationic moieties is of the order of 50-degrees. The crystal structure seems to be stabilized by ionic and van der Waals interactions as no hydrogen bond's have been observed.
