| Abstract: | Two conformers of Et4N]3Fe3(PhS)3Cl3Br3] were prepared through 1 step reaction of FeCl2 with NaSPh and Et4NBr in MeCN. The skeletons of the anions are 6-membered rings with alternative Fe and S arrangement, 1 existing in twist boat form and the other in a chair form. Crystals are monoclinic, space group C2/c, Z = 4, R = 0.070, and trigonal, space group P3c1, Z = 4, R = 0.059, resp. The characteristics of the reaction and structures are discussed. |
