The asymmetric unit of the title compound, C18H20N2S4, contains one half-molecule, the complete molecule being generated by a twofold rotation axis. The plane through the NCS2 group [maximum deviation = 0.01 (7) Å] is orthogonal to the phenyl ring, forming a dihedral angle of 89.4 (3)°. The crystal structure is stabilized by intermolecular C—Hπ interactions.

The title compound, C32H29NP2S2, has two molecules in the asymmetric unit, with an r.m.s. difference of 0.218 Å in their best-fit overlay. Both molecules have a slightly distorted trigonal–planar N atom, bonded to two PV atoms and a C atom of the 4-ethylphenyl 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—Hπ interactions. The methyl group in one of the molecules is disordered over two sets of sites, with occupancies of 0.518 (6) and 0.482 (6).
