The new zirconium phosphonate compound(NH4)Zr[F2][H3{O3PCH2NH(CH2CO2)2}2]·3H2O·NH4Clwas obtainedfrom the reaction of zirconyl chloride withN-(phosphonomethyl)iminodiacetic acid in the presenceof HF. Itcrystallizes in the triclinic space group P (No. 2)with a = 10.743(2) Å, b =11.483(2) Å, c = 5.330(1) Å, = 90.63(2), = 96.65(2), =97.68(2), and Z = 1. The structure consistsof linear chains of zirconiumatoms linked together by phosphonate oxygens. The zirconium atomis six-coordinated by four phosphonateoxygens and two fluoride ions. The compound represents the firstexample of a linear chain structure in thezirconium phosphate or phosphonate systems. The formation of suchlinear chains as opposed to the layeredstructure normally observed for zirconium phosphonates is attributed tothe bulkinesss of the phosphonic acid.
