摘要

摘要利用扫描电镜和 X 射线衍射方法研究了一种矿物，其成分为 Pd(Bi0.53Sb0.47)，介于索波列夫斯基（理想状态为 PdBi）和苏德伯里特（PdSb）之间，产自 Chineiskii 矿藏（俄罗斯外贝加尔地区）。根据单晶 X 射线衍射数据，解决并完善了其晶体结构（R = 3.02%）。晶体结构为正方晶系，空间群为 Cmcm。单位晶胞参数为 a = 4.1465(4) Å, b = 7.1782(6) Å, c = 5.6843(4) Å, V = 169.19(2) Å3, Z = 2。讨论了β-PdBi-Pd(Bi0.53Sb0.47)-PdSb 和 sobolevskite-sudburyite 结构系列。

The Crystal Structure of a Mineral with the Composition Pd(Bi,Sb)

Abstract

A mineral with the composition Pd(Bi_0.53Sb_0.47), intermediate between sobolevskite, ideally PdBi, and sudburyite, PdSb, from the Chineiskii Deposit (Transbaikal region, Russia), was studied by the SEM and XRD methods. Its crystal structure was solved and refined (R = 3.02%) based on single crystal X-ray diffraction data. The structure is orthorhombic, and the space group is Cmcm. The unit-cell parameters are a = 4.1465(4) Å, b = 7.1782(6) Å, c = 5.6843(4) Å, V = 169.19(2) Å³, Z = 2. The series of the structures β-PdBi–Pd(Bi_0.53Sb_0.47)–PdSb and sobolevskite–sudburyite are discussed.
