Ab-initio powder structure determination of dichloro[1,2ethanediylbis(iminomethylene)bis(phosphonato)]trizinc dihydrate Academic Article uri icon


  • The reaction of zinc chloride with 1,2-ethanediylbis(imino-methylene) bis(phosphonic acid) in acidic conditions yielded dichloro[1,2- ethanediylbis(iminomethylene)bis(phosphonato)]trizinc dihydrate, Zn 3Cl2(HO3PCH2NHCH2CH 2NHCH2-PO3H)22H 2O which crystallizes in the monoclinic system and space group P21/n, with the unit cell parameters a = 9.94316(4), b = 10.44577(5), c = 24.3240(1) , = 90.003(1), and Z = 4. The crystal structure was determined ab initio from its powder pattern using the programs EXPO and GSAS. The zinc atoms are in tetrahedral environment and form 16-membered rings with the phosphonate groups. The structure is clearly different from that of the corresponding Cd complex in that the Cd is sixfold coordinated and of different ligand to metal ratio. Wiley-VCH Verlag GmbH & Co.
