1-(Bromo-mercurio)ferrocene.

ABSTRACT: The asymmetric unit of the title compound, [Fe(C5H5)(C5H4BrHg)], contains two independent mol-ecules, A and B, in which the Hg-C bond lengths are 2.045?(6) and 2.046?(6)?Å, the Hg-Br bond lengths are 2.4511?(9) and 2.4562?(7)?Å, and the C-Hg-Br angles are 176.42?(17) and 177.32?(17)°. The two cyclo-penta-dienyl rings of mol-ecule A are eclipsed, while those of mol-ecule B are almost staggered. The HgBr groups are connected by inter-molecular Hg?Br contacts of 3.3142?(9)-3.4895?(11)?Å, forming layers parallel to (001). These layers contain both four-membered (HgBr)2 and eight-membered (HgBr)4 rings. Ferrocene-ferrocene C-H?? contacts connect the mol-ecular layers along the c-axis direction.
