Abstract

By reaction of Rh₂(O₂CCF₃)₄ and Mo(CO)₆ in an evacuated sealed tube placed in a thermal environment where there is a thermal gradient (125-120°C), we have obtained a compound in which one Rh₂(O₂CCF₃)₄ unit is sandwiched between two Rh₂(O₂CCF₃)₂(CO)₄ units, to give an essentially linear array of six rhodium atoms, with Rh-Rh distances of 2.960(1), 2.790(1) and 2.412(1) Å. These arrays of six rhodium atoms are then linked into infinite chains which lie parallel in the crystal, with Rh to Rh contacts of 3.062(1) Å. The crystals are markedly dichroic and relatively air stable.
