Abstract: The title compound (2,2,2-tris(cyclohexyloxy)phenanthro[9,10-d][1,3,2]dioxaphosphole), C₃₂H₄₁O₅P, displays trigonal-bipyramidal geometry at the central P atom. The P-O bond lengths (Å) are: in the five-membered ring 1.652  (2)  Å equatorial and 1.744  (2)  Å axial, and to the cyclohexyloxy groups 1.581  (2) and 1.589  (2)  Å equatorial, and 1.624  (2)  Å axial.
