Abstract
By reaction of Rh-2(O2CCF3)(4) and Mo(CO)(6) in an evacuated sealed tube pl aced in a thermal environment where there is a thermal gradient (125-120 de grees C), we have obtained a compound in which one Rh-2(O2CCF3)(4) unit is sandwiched between two Rh-2(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) Angstrom. These arrays of six rhodium atoms are then linke d into infinite chains which lie parallel in the crystal, with Rh to Rh con tacts of 3.062(1) Angstrom. The crystals are markedly dichroic and relative ly air stable. (C) 2000 Elsevier Science S.A. All rights reserved.
