The crystal and molecular structures of 2,2,3,3,5,5,6,6-octaphenyl-2,3,5,6-tetrastannacyclohexane were determined from three-dimensional X-ray data. The crystals are triclinic, space group P1. The unit-cell, with dimensions a 9.490(2), b 10.202(2), c 12.260(3) Å, α 103.43(2), β 78.09(2), γ 93.06(2)°, contains one molecule. The structure was solved by the Patterson method and refined to a final R value of 0.032 for 3190 independent reflections. The tetrastannacyclohexane ring has a chair conformation. The tintin bond length is 2.78 Å.
