Rapid ring-opening reactions of trans-[OsX2(dppm-P,P′)2] with [Rh2X2(CO)4](X = Cl or Br) to give osmium–rhodium heterobimetallics: crystal structure of [Cl2Os(µ-CO)2(µ-dppm)2RhBr](dppm = Ph2PCH2PPh2)
Abstract
Complex of the type [Y2Os(µ-CO)2(µ-dppm)2RhX](Y = Cl or Br: X = Cl, Br, I, SCN, or N3) have been made either as described in the title or by metathesis; the crystal structure and the i.r. spectrum of the title compound suggest strongly bridging CO groups.
