Structural investiagations of zirconium tetra-acetate and the group IVB tetra-acetates

Article abstract of DOI:10.1016/0584-8539(86)80039-3

Solid-state i.r., Raman 1H and 13C NMR spectra are reported for solid zirconium tetra-acetate and for the group IVB tetra-acetates (M=Si, Ge, Sn or Pb).The types of acetate co-ordination have been identified: Zr(OAc)4 has a polymeric eight-co-ordinate structure and contains both bridging and bidentate acetate groups; Si(OAc)4 and Ge(OAc)4 contain only unidentate acetates to give four-co-ordinate structures while Sn(OAc)4 and Pb(OAc)4 contain only bidentate acetate groups to give eight-co-ordinate monomeric structures.The solid-state Raman 13C NMR spectra are reported for the first time.
