Tetra­hydro­thio­phene tris­(penta­fluoro­phenyl)­borane

In the title compound, (C4H8S)B(C6F5)3, a comparatively long boron–sulfur distance of 2.0843 (16) A is found, most probably due to the sterically demanding penta­fluoro­phenyl­substituents. Bond distances and angles of the boron–aryl fragment are comparable to those found for uncoordinated MeB(C6F5)3− anions.
