In two polymorphs of the tetrahydrofuran disolvate of 2,5-[(diphenylphosphanyl)methyl]-1,1,2,4,4,5-hexaphenyl-1,4-diphospha-2,5-diboracyclohexane and a pseudo-polymorph of the toluene solvate, the crystal packings are significantly different, but, surprisingly, their molecular conformations are the same.
