Zn(O3POC2H5)-H2O crystallizes in the orthorhombic space group Pbca with a = 7.942 (3) A, b = 20.554 (5) A, c = 7.774 (2) A, V = 1268.9 (7) 3, and Z = 8; Zn(O3POC2H4NH3)(O2CCH3) crystallizes in the same space group with a = 9.655 (14) A, b = 23.692 (13) A, c = 7.934 (7) A, V = 1815.9 (31) A3, and Z = 8. Both compounds have layers formed by phosphate groups bridging the tetrahedral zinc atoms, which undulate perpendicular to the layer direction. The layers in the ethyl phosphate structure are centered at y =1/4and3/4and in the aminoethyl derivative at y = 0 and1/2The spacing between successive layers is determined by the pendant groups: the ethyl group in the ethyl derivative and the acetate group in the amino compound. The amino groups fold back upon themselves to hydrogen-bond to the acetate groups. Hydrogen bonding produces sheetlike structures with only van der Waals forces holding adjacent sheets together. 1989, American Chemical Society. All rights reserved.
