The crystal structures of four phosphorus-containing polyoxamacrocycles 2,4, 6,11,13-Pentachloro-dibenzo[d,g][1,3,9,2]trioxaphosphacycloundecan-2-thione (1),2,4,9,14, 16-Pentachloro-dibenzo[g,j][1,3,6,12,2]tetraoxaphosphacyclotetra- decan-2-thione (2), 2,4, 10,16,18-Pentachloro-dibenzo[h,k][1,3,7,12,2]tetraoxa- phosphacyclohexadecan-2-thione (3) and 2,4,6,12,14,18,20,28,30 - Nona-chloro-tetrabenzo[d,g,p,s] [1,3,9,13,15,21,2,14]hexaoxa diphosphacyclotetracosan-2,14-dithione (4) have been determined by X-ray diffraction. The result shows that compound 4 has a center of symmetry, and compounds 1, 2, and 3 have no elements of symmetry. The molecules of compounds 2 and 4 form inclusion complex with neutral molecule guest (CHCl3) which is outside of the phosphorus-containing macrocycle in the ratio of 1:1, and compounds 1 and 3 do not form inclusion complexes with CHCl3. The result obtained in this paper lays a foundation for further research on the complexing properties of phosphorus-containing polyoxamacrocycles.
