Kagomé nets of corner-connected triangles of atoms occur in diverse minerals, from the {111} anion arrays in perovskite-group minerals to natural metallic alloys like auricupride, AuCu3, to the cation layers in atacamite-group minerals. We review here two- and three-dimensional kagomé networks in minerals where the kagomé node atoms are octahedrally coordinated in hexagonal tungsten bronze (HTB) arrays. Octahedral tilting, coupled with capping of the apical anions of the triangular groupings of octahedra in the HTB layers, gives rise to several important mineral groups, including pyrochlores, alunite-supergroup minerals, zirconolite and weberite polytypes and spinel-group minerals, as a function of the magnitude and type of the octahedral tilting.

矿物中八面体配位金属原子的Kagomé网络:通过八面体倾斜来关联不同的矿物结构

原子的角连接三角形的Kagomé网存在于多种矿物中,从钙钛矿族矿物中的{111}阴离子阵列到auricupride,AuCu 3之类的天然金属合金,到钽铁矿族矿物中的阳离子层。我们在这里回顾矿物中的二维和三维卡戈米网络,其中在六角形钨青铜(HTB)阵列中,卡戈米节点原子是八面体配位的。八面体倾斜以及HTB层中八面体三角形组的顶部阴离子的封端产生了一些重要的矿物群,包括烧绿石,亚铝矾土-超群矿物,锆石和韦伯岩多型体以及尖晶石族矿物八面体倾斜的大小和类型。
