The position of americium within lanthanides in respect to unit cell volumes has been determined for 25 isostructural MmXn compounds. A linear correlation between the position of americium and the electronegativity of X atom has been demonstrated. This result has been explained in terms of greater covalent shortening of Am-X than of Ln-X bonds.

已经确定了25种同构MmXn化合物中镅在镧系元素中相对于单位细胞体积的位置。证明了镅的位置与X原子的电负性呈线性相关。这一结果可以用Am-X键比Ln-X键的共价缩短来解释。

The rate constant for the photon-activated oxidation of aliphatic alcohols by HCro4− is shown to obey a linear free-energy relation that suggests a two electron-transfer rate-determing step.

HCro4−对脂肪族醇进行光子活化氧化的速率常数服从线性自由能关系，表明存在两个电子转移速率决定步骤。

The electrochemical oxidation of anodic zinc into a solution of PhSH + Et3N in CH3CN yields *Et3NH)2[Zn4(SPh)10]. The structure, as determined by X-ray crystallography, shows that the anion is a novel cluster based on a tetrahedral Zn4S10 kernel.
