%X In the title compound, C24H56N4P2, the distance between the P atoms [2.2988 (8) and 2.3013 (13)   in the major and minor occupancy components, respectively] is one of the longest reported for uncoordinated diphosphanes. The whole molecule is disordered over two positions with site-occupation factors of 0.6447 (8) and 0.3553 (8). The structure adopts the synperiplanar conformation in the solid state [N¡ªP¡ªP¡ªN torsion angle = 14.7 (5)¡ã].
