 Title    |Fe4S4I2(C6H 10(N HCSNHMe)2)]: ein neutraler Eisen-Schwefel-Cluster mit zweizähnigem Liganden [Fe4S4l2(C6H 10(NHCSNHMe)2)]: A Neutral Iron-Sulfur Cluster with a Bidentate Ligand  
 Abstract    The reaction o f [Fe4S4I2(SC (N M e2)2)2 ] with racemic l,2-bis(3-m ethylthioureido)-cyclohexane in tetrahydrofuran (thf) yields [Fe4S4I2(C 6H 10(N H C S N H M e)2)]-4 th f (2). 2 crys­ tallizes in the monoclinic space group C 2/c with a = 1471.7(2), b = 1329.7(2), c = 2339.3(3) pm, ß = 107.70(1), V = 4362.3 x 106pm 3, Z = 4, R -0.057. The cluster exhibits C2 symmetry in the solid state. The replacement o f the m onodentate neutral ligands results in a cluster in which the bifunctional thiourea derivative bridges tw o different iron sites o f the slightly com ­ pressed [Fe4S4] core. The most striking feature are the differences o f the F e -F e distances which are 269.8 pm between thiourea coordinated atom s and 280.7 pm between Fe atom s with iodide ligation. The F e -S thiourea distance was found to be 229.3 pm.
