Tris(0-4-tert-Butylphenyl) Thiophosphate, C30H39O3PS

Abstract

The P-O bond of the title compound is aligned along a threefold symmetry axis, making the three 4-(tert-butyl)phenyl groups crystallographically equivalent. The P atom is bonded to three O and one S atom, forming a distorted tetrahedron: O-P-S = 117(1), O-P-O = 100 (1)degrees, PS = 1.908 (1), P-O = 1.579 (2) Angstrom. Neither the phenyl ring nor the attached tert-butyl group exhibit any unexpected geometrical features.
