title: N,N-Bis(diphenyl-thio-phosphino-yl)-4-ethyl-aniline.
abstract: The title compound, C32H29NP2S2, has two mol-ecules in the asymmetric unit, with an r.m.s. difference of 0.218 Å in their best-fit overlay. Both mol-ecules have a slightly distorted trigonal-planar N atom, bonded to two P(V) atoms and a C atom of the 4-ethyl-phenyl unit. The P-N-P angles of 126.34 (11) and 125.98 (11)° are larger than the four C-N-P bond angles. The two S atoms are trans to one another with respect to the P-N-P angle. The crystal structure features C-H⋯π inter-actions. The methyl group in one of the mol-ecules is disordered over two sets of sites, with occupancies of 0.518 (6) and 0.482 (6).
