Crystal structure of n ‐phenyl‐2,4,6‐triphenyl perchlorate, C 29 H 22 ClO 4

The crystal structure of n ‐phenyl‐2,4,6‐triphenyl perchlorate has been determined using the direct methods technique and refined to R o = 0.055 and R w = 0.056 for 1321 unique reflections measured on four‐circle diffractometer in the w scanning mode MoKα radiation. The crystals are orthorhombic, Pbca, a = 16.611(9), b = 16.625(6), c = 17.554(5) Å and Z = 8. All rings are planar as expected within the experimental errors. Rings B, C, D, and E are twisted about the formal single bond by 72, 19, 95, and 78°, respectively, out of the plane of the central ring.
