High Quality Content by WIKIPEDIA articles! Octahedral clusters are inorganic or organometallic cluster compounds composed of six metals in an octahedral array. One important class of octahedral clusters are chalcohalide clusters of the type M6X8L6 where M is a metal usually of group 6 or group 7, X is a ligand and more specifically an inner ligand of the chalcohalide group such as chlorine or sulfur and L is an "outer ligand." The metal atoms define the vertices of an octahedron. The overall point group symmetry is Oh. Each face of the octahedron is capped with a chalcohalide and eight such atoms are at the corners of a cube. For this reason this geometry is called a face capped octahedral cluster. Examples of this type of clusters are the Re6S8Cl64- anion and the W6I142- anion, the last one by reaction of tungsten hexacarbonyl with iodine at elevated temperatures. Molybdenum(II) chloride is an example of a polymeric octahedral cluster; it reacts with chloride sources to afford Mo6Cl142-.
