square positions are statistically occupied by Ru and Fe. [54] The FeRuS2 base is not an ideal planar with a mean deviation from the plane of 0.146 Å. The angles at the sulfur atom are (M(1)-S(1)-M(2) = 97.82(5)o and M(l)-S(2)-M(2) = 97.72(5) o, where M =1/2Fe + 1/2Ru). Similar crystallization was also found in the structure of [Et4N][Se2F2Mn(CO)9] [54]. The two phosphorus atoms of Ph2PCH2PPh2 resides in the apical-apical position of the square-pyramidal geometry of the M1 and M2 atoms, close to the solid-state structure of Fe3S2(CO)7(dppm) and Fe3S2(CO)7(dppf) [34].<br>3.3 Synthesis and characterization of complexes 7a, 7b and 8a, 8b.<br>Scheme 4<br>In order to further develop the novel reactions of ruthenium-arene complexes (arene)Ru2Cl4, the reactions of (arene)Ru2Cl4 and two-μ-CS2-containing dianion [{μ-S(CH2)3S-μ}{(μ-S=CS)Fe2(CO)6}2]2− which prepared by reaction of two μ-CO-containing dianion [{μ-S(CH2)3S-μ}{(μ-CO)Fe2(CO)6}2]2- with CS2 were conducted [55, 56]. Finally, some interesting results were obtained, two isomers of the macrocyclic (η6-arene) Ru-bridged complexes 7a, 7b and 8a, 8b containing four butterfly [Fe2SC=S] cluster cores were firstly isolated (Scheme 4) with total yields of 15.0% and 13.1%, in which the propylene group were attached to two S atoms in ee and ea modes. <br>Complexes 7 and 8 are somewhat air-sensitive red-brown solids and are characterized by elemental analysis and spectroscopic techniques. The IR spectra of 7 and 8 displayed four strong absorption bands in the range of 2072-1974 cm-1 for their terminal CO’s and one medium absorption band in the region of 999 cm−1 for their μ-C=S groups. The 13C NMR spectra of 7 and 8 exhibited 4 singlets between 202.8-213.3 ppm for their carbonyl C atoms, and displayed two singlets between 262.3 - 317.7 ppm for their µ-CS2 groups.
