Kobellite is a Pb-Bi-Sb sulfosalt with minor amounts of (Cu, Fe) and with the crystal structure composed of two types of rods, one of which has unusual lateral extensions (‘lobes’), which depart from the usual lozenge-shaped rod cross-section in sulfosalts. Several Pb-Bi-Sb and Pb-Sb-rich sulfosalts form a small group built on similar principles. Some of them are related by homology (e.g., izoklakeite), and differ by the perpendicular dimensions of rods (length and multiplicity of atomic layers in a rod; e.g., sterryite), and especially by different combinations of archetypes and archetype portions which participate in the rods (PbS archetype and the two orientations of SnS archetype). The present article summarizes and discusses the published data on the group. Homeotypism makes the group interesting and potentially a fertile source of further structural varieties.

神贝利石是一种 Pb-Bi-Sb 硫盐，含有少量（Cu、Fe），其晶体结构由两种棒状体组成，其中一种具有不寻常的横向延伸（“裂片”），与通常的菱形不同。硫盐中的异形棒横截面。几种 Pb-Bi-Sb 和富含 Pb-Sb 的磺盐形成了一个基于相似原理的小组。其中一些通过同源性相关（例如，izoklakeite），并且由于杆的垂直尺寸（杆中原子层的长度和多重性；例如，菱镁矿）而不同，尤其是参与参与的原型和原型部分的不同组合。棒（PbS 原型和 SnS 原型的两个方向）。本文总结并讨论了该小组已发表的数据。同型论使这个群体变得有趣，并且可能成为进一步结构变异的丰富来源。
