Abstract: The crystal and molecular structures of [(C3H7O)2PS2]2 (CCDC No.217201) were determined by means of X-ray crystallography. It crystallized in a triclinic system with space group P-1 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, [(C3H7O)2PS2]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 P＝S bonds in the two dithiophosphate units are trans-oriented to each other.
