Crystal structures of eight- and ten-membered cyclic bis-anisyl-phosphono-thioyl disulfanes and comparison with their P-ferrocenyl analogues.

ABSTRACT: Two new crystal structures of eight- and ten-membered cyclic bis-anisyl-phosphono-thioyl disulfanes, namely 2,5-bis-(4-meth-oxy-phen-yl)-1,6,3,4,2λ⁵,5λ⁵-dioxadi-thiadi-phospho-cane-2,5-di-thione, C₁₆H₁₈O₄P₂S₄, and 2,5-bis-(4-meth-oxy-phen-yl)-1,6,3,4,2λ⁵,5λ⁵-dioxadi-thia-diphosphecane-2,5-di-thione, C₁₈H₂₂O₄P₂S₄, have been determined and compared to structures of the ferrocenyl analogues. The eight-membered rings have similar conformations (TBC) but the ten-membered macrocycles are differently puckered. Structural parameters of the relevant SPSSPS motif have been analysed and are discussed in detail. Compound 1 was refined as an in
