Oxysalts, Intermetallics and Mineral Systematics

复杂含氧盐中阳离子质心关联的最新进展 金属间化合物中的金属质心，促使我探索 复杂的结构类型，其中一些在自然界中出现的大 晶体，包括地金砷铜矿，硫砷铜矿，硫砷铜矿， 硅镁矾、硅镁矾、硅镁矾和硅镁矾。 为什么这样做 复杂的结构存在于通常形成大的 水晶？ 迪钦苏铁结构类型出现在晶体中， 1 m3，在不对称单元中有47个原子。 PI计划 为这些结构寻找合适的单元转换， 适当的金属间化合物进行比较。 他希望 预测孤对电子的取向，v，在环境中， 配位阴离子。 这利用了鲍林的基本原理 静电价规则 据信，这种方法 将有助于整理出无数的铅氧盐结构 这是目前已知的。 最后，体积贡献 硫盐矿物中钒的含量可以合理化。

Recent success in relating cation centroids in complex oxysalts to metal centroids in intermetallics has motivated me to explore complex structure types, some which occur in nature as large crystals, including dickinsonite, alluaudite, graftonite, griphite, triplite, triploidite and grischunite. Why do such complex structures exist in phases which often form large crystals? Dickinsonite structure type occurs in crystals up to 1 m3 and has 47 atoms in the asymmetric unit. The PI plans to seek out appropriate cell transforms for these structures, and the appropriate intermetallic for comparison. He hopes to predict the orientation of the lone pair, v, in an environment of coordinating anions. This exploits the fundamental Pauling electrostatic valence rules. It is believed that this approach will aid in sorting out the myriad plumbous oxysalt structures which are presently known. Finally, the volumetric contribution of v in the sulfosalt minerals can be rationalized.
