In the molecular crystal of hexaphenylhexaphosphinane benzene solvate, C36H30P6· C6H6, representing the trigonal form of phosphobenzene as a solvate, the six-membered ring of P atoms adopts a chair conformation wherein the six phenyl groups are located in equatorial positions. The molecules [molecular symmetry\ overline {3}(C3i)] are stacked infinitely along the c-axial direction.
