Crystal Structure of Bis(O,O′-diisopropyl dithiophosphate): (C_3H_7O)_2PS_2_2

摘要

The crystal and molecular structures of [(C 3H 7O) 2PS 2] 2(CCDC No.217201) were determined by means of X-ray crystallography. It crystallized in a triclinic system with space group P1 and lattice parameters a=0.82794(3) nm, b=0.84764(2) nm, c=0.85034(3) nm, α=97.78(3)°, β=110.77(3)°, γ=94.95(3)°, V=0.54701(9) nm3, Z=1. In this molecule, the two diisopropyl dithiophosphate groups, [(C 3H 7O) 2PS 2] 2, which are parallel to each other, are linked by an S—S bond and there exist inversion centers in the molecule. In the structure, the PS bonds in the two dithiophosphate units are trans-oriented to each other.
