Different SbN and SbCl distances for equivalent Sb atoms are observed for the four‐membered ring 1 (the structure shown omits the substituents attached to S). The Sb atoms are considered to have pseudo‐trigonal‐bipyramidal coordination in which the N atoms of Sb1 occupy equatorial and the Cl atoms axial positions whereas the two axial positions of Sb2 are filled by one N and one Cl atom, as are the two equatorial positions.
