Abstract

Three new chalcogen-bridged mercury-iron clusters with 7, 14, and 39 mercury centers were obtained from the reaction of tBuSSiMe<sub>3</sub> with [Fe(CO)<sub>4</sub> (HgX)<sub>2</sub> ] (X= Cl, Br). The compounds were isolated in the form of orange crystals that were characterized by X-ray crystallography. The picture on the right shows the structure of the heavy-atom skeleton of [Hg<sub>14</sub> Fe<sub>12</sub> {Fe(CO)<sub>4</sub> }<sub>6</sub> S<sub>6</sub> (StBu)<sub>8</sub> Br<sub>18</sub> ] (Hg, Fe, Br, and S are black, diagonally striped, white, and horizontally striped, respectively).
