C34H88O2N4Mo2Fe2S10, Mt= 1209. 25,monoclinic, P21/a,a= 17. 722 (7) ,b= 11. 857(5),c= 13. 743(5) A .β= 112. 29 (3)°, V= 2672. 0A3,Z = 2,Dc = 1. 503 g·cm-33,μ(Moka) = 14. 0 cm-1,T=193 K. Final R=0. 045 for 1943 observed reflections (I≥3σ(I)). In the anion [(MoS4)_2Fe2S2]4- ,the two Fe atoms, each attached with a chelating MoS42- unit, are bridged by two sulfur atoms. The metal atoms are arranged in a linear fashion with Mo-Fe-Fe angle of 179. 1(1)°, and Fe-Fe and Fe-Mo distances of 2. 746(2) and 2. 801(2) A, respectively. The long Fe-S distances (average 2. 246A) in Fe2S2 ring could be a result of the hydrogen-bonding interaction between the sulfur atom and the methanolic hydrogen atom.
