title: 5-Benzyl-idene-2,3-diphenyl-1,2-selenaphosphole-2-selenide.
abstract: The title compound, C(23)H(19)PSe(2), has a central five-membered twist C(3)PSe ring conformation. One phenyl ring substituent, attached to an sp(2) carbon, is approximately coplanar with the C(3)PSe ring whilst the other organic substituents, attached to an sp(3)-carbon and a P(V) atom, lie on the same side of the ring.
