چکیده
In the title compound, [Fe(4)(C(6)H(12)N(2)S(4))(C(18)H(15)P)(2)(CO)(10)], the unit cell contains one mol-ecule, which exhibits a crystallographically imposed center of symmetry. The independent Fe(2)S(2) fragment [Fe-Fe = 2.527 (1) Å] is in a butterfly conformation, and each Fe atom displays a pseudo-square-pyramidal coordination geometry. The phosphane group occupies an apical position [Fe-P = 2.2670 (14) Å]. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into chains along [110].
