font lang="en" face="AdvTimes" size="1"> Interlayer acetate anions in layered double hydroxyacetates of Ni2+ and Zn2+ have been exchanged by oxovanadates following three synthetic routes (at 60ºC, under hydrothermal conditions and after preswelling with caprylate anions) and different pH; direct exchange at room temperature was not successful. Complete exchange was achieved under adequated conditions, and the precise nature of the interlayer anion depends on the pH during exchange: at low pH (4.5), the presence of alfa-VO3 chains, with anchoring (grafting) of the
