Tris(4-methyl-phen-yl)phosphine selenide.

ABSTRACT: In the title mol-ecule, C(21)H(21)PSe or PSe(C(7)H(7))(3), the P atom has a distorted PSeC(3) tetra-hedral environment, formed by the Se atom [P=Se = 2.1119?(5)?Å] and three aryl rings. Two short intra-molecular C-H?Se contacts occur. In the crystal, weak inter-molecular C-H?Se inter-actions link the mol-ecules 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.
