Abstract
In the title compound, C25H22P2Se2 (dppmSe(2)), the methylene C atom l ies on a crystallographic twofold axis, in contrast to the previously known modification, which had no imposed symmetry, The conformation is expressed by the torsion angle Se-P ... P-Se 148.12 (7)degrees. Bond lengths and angles are similar to those in other dppmX(2) molecules.
