Abstract The crystal structure of [(n-C4H9)4N]2[Pt2I6] has been determined from X-ray data measured by counter methods. It crystallizes in the monoclinic space groupP21/c (C 2h -5 , No. 14) with unit cell constantsa=14.457(4),b=14.036(4),c=23.696(5) Å,β=101.02(3)°, andD c =2.30 g cm−3 forZ=4. Full-matrix least-squares refinement led to a finalR value of 0.049 for 1786 independent observed reflections. The [Pt2I6]2− anion is planar to within 0.07 Å and exhibits an average Pt-I bridging bond length of 2.559(4) Å and average Pt-I terminal distance of 2.571(7) Å. Of the two independent [(n-C4H9)4N]+ cations, one approaches a ¯42m-D 2d conformation, the other an approximate ¯4-S4 conformation.
