The title compound, Zn(O3PCH2NH2CH2CH2NH3)Cl2, crystallizes in the monoclinic space group P21/c with Z =4 and cell parameters a = 8.348(1), b = 8.269(1), c = 15.220(2)Å β = 103.29(1)°, V = 1022.5(2)Å3. The zinc ion is 4-coordinate being bonded to two chloride ions and two oxygen atoms. Polymeric chains of Zn atoms bridged by the phosphonato group form in a zig zag manner in the crystallographic b direction. A strong hydrogen bonding scheme. involving both Cl- ions and the third phosphonato oxygen atoms as acceptors and the protonated amino groups as donors together with the interpenetrant packing of the amine chains causes the structure to be strongly bound in three dimensions. © 1989, Taylor & Francis Group, LLC.
