The asymmetric unit of the title salt, [C22H20O2P]2 (+)TeI6, consists of one triphenyl(5-oxooxolan-3-yl)phosphanium cation and one half of a hexa-iodido-tellurate(IV) dianion. The Te atom is located at an inversion centre and is octa-hedrally coordinated by six I atoms. The Te-I bond lengths range from 2.9255 (9) to 2.9439 (10) Å. The I-Te-I angles between cis-iodide ligands are in the range 87.85 (3)-92.15 (3)°. In the crystal, the components are connected by C-H⋯I inter-actions. In the final refinement of the compound a void of 32 Å(3) was observed.
标题盐[C22H20O2P]2(+)TeI6的不对称单元由一个三苯基(5-氧代氧杂环戊烷-3-基)鏻阳离子和一个六碘合碲(IV)二价阴离子的一半组成。碲原子位于一个对称中心，由六个碘原子八面体配位。碲-碘键长范围为2.9255 (9)至2.9439 (10) Å。顺式碘配体之间的碘-碲-碘角度在87.85 (3)-92.15 (3)°范围内。在晶体中，各组分通过C-H⋯I相互作用相连。在该化合物的最终精修中，观察到一个32 Å(3)的空洞。
