Pb2(Hg3O4)(CrO4) consists of [CrO4]2- tetrahedra, linear O-Hg-O dumbbells and divalent Pb atoms in [3+5]-coordination. The HgO2 dumbbells are condensed into [Hg3O4]2- units and can be regarded as a section of the HgO structure. The [Hg3O4]2- complex anions are connected by interstitial Pb2+ ions, while the [CrO4]2- tetrahedra are isolated.
Pb2(Hg3O4)(CrO4)由[CrO4]2-四面体、线性O-Hg-O哑铃结构以及处于[3 + 5]配位的二价Pb原子组成。HgO2哑铃结构缩合形成[Hg3O4]2-单元,可被视为HgO结构的一部分。[Hg3O4]2-复合阴离子通过间隙Pb2+离子相连,而[CrO4]2-四面体则是孤立的。
