: The crystal structure of Zn 8-hydroxyquinolinate dihydrate was determined by single crystal methods. THe unit cell is monoclinic with a = 11.28 A, b= 5.42 A, c =13.16 A. and beta = 106 deg 18 ft. The space group is P2 sub 1/ a -(c(superscript5)) sub 2h; there are 2 molecules per unit cell. Atomic positions were determined by Fourier projections and refined by a 3-dimensional Fourier electron-density synthesis and by the method of least squares. Structural factors were obtained from visually estimated intensities on Weissenberg photographs taken with Cu K alpha radiation. The molecule, with the exception of the Hsub2O groups is essentially planar. When the Hsub2O molecules are included, A distorted octahedral arrangement of bonds results around the central Zn ion. The Zn-O and Zn-N bond lengths are 2.05 A and 2.06 A, respectively; the Zn-OHsub2 bond length is 2.27 A.
