| Abstract: Molybdcnum-iron-sulfur cluster complex, [Fc(2,2'-bpy)3][S2MoS2FcCI2] was prepared from the reaction of(Et4N)2MoS4,FeCl2 and 2,2'-bpy in acctonitrilc. The crystal belongs to monoclinic space group P21/c with a=9.328(3), b=26.788(2), c=13.764(3)Å, β=95.38(3)° ; V=3424.2(11)Å3;Z=4; Dc=1.698gcm-3. The crystal structure was solved by direct methods and refined by full-matrix least-squares techniques for 3933 reflections with I>3δ(I0). The final R and Rω are 0.068 and 0.071, respectively. In the crystal, the [S2MoS2FcCI2]2- anion are situated at the vacancies formed by the cations. There is no disordered arrangement of metal atoms in the title anion. At a result, its structural parameters have been determined accurately. The core of the anion MoS2Fe is planar with Mo…Fe distance of 2.773(2)Å, and the distances of bonds Mo-Sb and Fe-Sb arc nearly equivalent within the range of 2.248-2.251Å |
