Tris(4-methyl­phen­yl)phosphine selenide

In the title mol­ecule, C(21)H(21)PSe or PSe(C(7)H(7))(3), the P atom has a distorted PSeC(3) tetra­hedral environment, formed by the Se atom [P=Se = 2.1119 (5) Å] and three aryl rings. Two short intra­molecular C—H⋯Se contacts occur. In the crystal, weak inter­molecular C—H⋯Se inter­actions link th...

Sumario:In the title mol­ecule, C(21)H(21)PSe or PSe(C(7)H(7))(3), the P atom has a distorted PSeC(3) tetra­hedral environment, formed by the Se atom [P=Se = 2.1119 (5) Å] and three aryl rings. Two short intra­molecular C—H⋯Se contacts occur. In the crystal, weak inter­molecular C—H⋯Se inter­actions link the mol­ecules into zigzag double chains propagating in [100]. The previous report of this structure [Zhdanov et al. (1953 ▶). Dokl. Akad. Nauk SSSR (Russ.) (Proc. Nat. Acad. Sci. USSR), 92, 983–985] contained no geometrical data.
