 To a suspension containing [Bu4N]2[Re2Cl8] in ethanol few drops of
 concentrated HCl were added. The mixture was cooled to 0 C and
 PEt2H was syringed to the suspension. It was stirred for 4 hours
 at 0C, then slowly warmed to room temperature. The resulting green
 solid was separated by filtration. Single crystals were obtained
 by slow diffusion of isomeric hexanes into dichloromethane
 solution.
