<正> Mr= 873.02, orthorhombic P21212, a= 16.153(3), b= 15.718(2), c= 8.847(3) A, V= 2246.2(14)A3, Z=2, Dx? 1.291gcm-3, MoK(?), radiation, λ= 0.71069A, μ= 9.417mm-1, F(000)= 924, R(Rw)= 0.073(0.069) for 1936 observed reflections. The structure of the anion contains a FesSz core, in which each iron atom is coordinated by two μ2-S atoms and two thiolate sulfur atoms to form a distorted tetrahedron.
