  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 1.09 nm 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.

  在不含水的乙二醇（EG）中，通过溶热反应成功合成了具有薄片结构的新型层状羟基乙酸锌（LZG）。在含水量为 1%的乙二醇中形成了八面体形的羟基乙酸锌（OZG）颗粒。LZG 和 OZG 是具有相同成分 Zn(OCH2CH2O) 的晶体多晶型。含水量为 5%时，形成了均匀的球形氧化锌颗粒。在醋酸锰溶液中，LZG 中的 EG 分子与醋酸锰络合物发生了部分交换，LZG 的层间距从 1.09 nm 增加到 1.42 nm。将交换后的 LZG 在 600 °C 下加热可形成 ZnO 和 ZnMn2O4。交换 LGZ 中的醋酸根离子被水杨酸根离子交换。OZG 中的 EG 分子主要与醋酸锰溶液中的 OH 交换，形成无定形相。

  The glycoxide complexes Zn(1-x) Co (x) (HCOO)(HOCH(2)CH(2)O)(1/2) and Zn(1-x) Co (x) (OCH(2)CH(2)O) (0 a parts per thousand currency sign x a parts per thousand currency sign 0.3) have been synthesized by heating ethylene glycol solutions of zinc formate Zn(HCOO)(2) center dot 2H(2)O or its mixtures with cobalt formate Co(HCOO)(2) center dot 2H(2)O. The crystals of these complexes have the shape of filaments (needles, bars) and distorted octahedra, respectively. A new method in which these complexes are used as the precursor is suggested for the synthesis of low-dimensional wurtzite-like Zn(1-x) Co (x) O. The shape of the precursor crystals is fully inherited by Zn(1-x) Co (x) O resulting from their heat treatment. The Zn(1-x) Co (x) O solid solutions show high photocatalytic activity in hydroquinone oxidation in aqueous solution under UV or blue light irradiation, and their activity increases as their cobalt content is increased.

  Nanotubes of manganese-doped zinc oxide Zn1-xMnxO (0 <= x <= 0.2) were synthesized by heating the Zn1-xMnx(HCOO)(OCH2CH2O)(1/2) precursor in air at 500 degrees C. The precursor with extended crystals was synthesized by a solvothermal method based on heat treatment of a mixture of Zn1-xMnx(HCOO)(2) center dot 2H(2)O with an ethylene glycol excess at 100-130 degrees C. The tubular morphology of Zn1-xMnxO particles was identified by transmission electron microscopy. Tubular quasi-one-dimensional particles were shown to have a nanodispersed polycrystalline structure, the size of separate crystallites being from 5 to 20 nm. X-ray photo-electron spectroscopy suggested that the manganese distribution on the outer surface layer of Zn1-xMnxO nanotubes is nonuniform.
