Abstract:	Conclusions An x-ray diffraction structural analysis showed that the P-diastereomer of 1,2;3,4;5,6-tris-O-(diethylamidothionephosphate)galactite (C₁₈H₃₈N₃O₆P₃S₁₈) with melting point 178.5-179C has terminal dioxaphospholane rings in a cis arrangement. One of these rings has planar conformation, while the other has twist conformation. These rings also differ in the configuration of the phosphorus atom. The central ring has twist conformation.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 6, pp. 1408–1410, June, 1988.
