Abstract
  • Zn(O3PCH2OH) (1) has been formed by reaction of zinc acetate with diethyl hydroxymethylphosphonate. Theacidity of the zinc solution effects hydrolysis of the phosphonate to produce phosphonic acid in situ.1 crystallizesin the trigonal spacegroup R3̄, with a = 15.9701(2) Å, c = 7.783(2) Å, and Z = 18. The compound has channelsin the [001] direction, formed by phosphonate groups bridging the octahedral coordinated zinc atoms. The zincatoms are coordinated by the three oxygens of the phosphonate group and the oxygen of the hydroxy group.
  • Zn(O3PCH2OH) has been formed by reaction of zinc acetate with diethyl hydroxymethylphosphonate. The acidity of the zinc solution effects hydrolysis of the phosphonate to produce phosphonic acid in situ. Zn(O3PCH2OH) crystallizes in the trigonal space group R3̄, with a = 15.9701(2) Å and c = 7.783(2) Å. The compound contains circular channels (diameter 3.8 Å) in the (001) direction, formed by phosphonate groups bridging the octahedrally coordinated zinc atoms. The hydroxy group participates in the coordination of the zinc atoms.
