The title compound, C28H33N2S2P, adopts the thione tautomeric form, as supported by the C-S distance [1.6744 (18) Å]. The Schiff base exhibits an E conformation about the C=N bond but a Z conformation about the C-N bond. The terminal chain is disordered over two sets of sites with an occupancy ratio of 0.732 (3):0.268 (3). In the crystal, pairs of N-N-H hydrogen bonds between the thione groups link neighbouring mol-ecules into centrosymmetric dimers.
标题化合物C28H33N2S2P采取硫酮互变异构形式,这由C-S键长[1.6744 (18) Å]所支持。席夫碱在C=N键周围呈现E构型,但在C-N键周围呈现Z构型。末端链在两组位点上无序,占有率为0.732 (3):0.268 (3)。在晶体中,硫酮基团之间的N-N-H氢键对将相邻分子连接成中心对称二聚体。
