The Crystal Structure of Bis(2,2′-bipyridyl)palladium(II) Picrate [Pd(bpy)2](pic)2. A Novel “Bow” Distortion

Abstract

Abstract The title complex crystallized in the triclinic space group P\barl with a=8.228(2), b=13.493(2), c=7.753(1)Å; α=96.96(1), β=106.16(1), γ=99.99(1)°; Z=1. The structure was solved by the heavy-atom method and refined by the block-diagonal least-squares method to R=0.0366. It is found that picrate ions above and below the [pd(bpy)2]2+cation stack with the bpy molecules and that this stacking leads to a novel bow distortion of the cation.
