The novel layered zinc glycolate (LZG) with a lamella structure was successfully synthesized from zinc acetate by solvothermal reactions in ethylene glycol (EG) without water. The octahedral-shaped zinc glycolate (OZG) particles were formed in EG containing 1% water. LZG and OZG are crystal polymorphs with the same composition, Zn(OCH2CH2O). At 5% water content, the uniform and spherical particles of ZnO were formed. EG moieties in LZG were partially exchanged with Mn acetate complex in Mn acetate solution and the interlayer spacing of LZG was increased from 1.09nm to 1.42 nm. ZnO and ZnMn2O4 were formed by heating the exchanged LZG at 600 °C. Acetate ions in the exchanged LGZ were exchanged with salicylic ions. EG moieties in OZG were mainly exchanged with OH in Mn acetate solution to form an amorphous phase.
