A magnesium citrate glycinate co-salt has a formula of Mg2C8H9NO9 - X H2O and a suggested structure of Formula I. The magnesium citrate glycinate co-salt has an apparent density of 1740 kg/m3 and is compressible in a range of compression pressures from approximately 50 MPa to approximately 150 MPa. The magnesium citrate glycinate co-salt is formed by combining citric acid and glycine in a 1:1 molar ratio to form an aqueous reaction mixture and neutralizing the aqueous reaction mixture with a magnesium source having a magnesium:ligand ratio of 1:1.
一种柠檬酸镁甘氨酸共盐的化学式为Mg2C8H9NO9 - X H2O,建议的结构如公式I所示。柠檬酸镁甘氨酸共盐的表观密度为1740千克/立方米,在约50兆帕至约150兆帕的压缩压力范围内可压缩。柠檬酸镁甘氨酸共盐是通过将柠檬酸和甘氨酸按1:1的摩尔比混合形成水溶反应混合物,并用镁源中和具有1:1镁:配体比的水溶反应混合物而形成的。

A new mixed valence Cu(III)/Cu(IV) has been stabilized in the three-dimensional lattice of the perovskite-type oxide La1-xSrxCuO3 (0 ≤ x ≤ 0.25). Chemical analysis and XPS studies confirm the mixed valence. This compound shows metallic properties with a broadening of the conduction band compared to that of LaCuO3. Such behavior can be explained either by the increase of the covalence of the average
一种新的混合价铜(III)/铜(IV)已经在钙钛矿型氧化物的三维晶格被稳定的La 1- X的Sr X的CuO 3(0≤ X ≤0.25)。化学分析和XPS研究证实了混合价。与LaCuO 3相比,该化合物具有导带扩宽的金属特性。可以通过增加平均Cu-O键的共价或通过减少Sr(II)代替La(III)引起的结构变形来解释这种行为。在温度低至4 K的材料中未检测到超导特性。
