Synthesis and properties of Rh(i) and Ir(i) distibine complexes with organometallic co-ligands

The first series of Rh(i) distibine complexes with organometallic co-ligands is described, including the five-coordinate [Rh(cod)(distibine)Cl], the 16-electron planar cations [Rh(cod)(distibine)]BF4 and [Rh{Ph2Sb(CH2)3SbPh2} 2]BF4 and the five-coordinate [Rh(CO)(distibine) 2][Rh(CO)2Cl2] (distibine = R 2Sb(CH2)3SbR2, R = Ph or Me, and o-C6H4(CH2SbMe2)2). The corresponding Ir(i) species [Ir(cod)(distibine)]BF4 and [Ir{Ph 2Sb(CH2)3SbPh2}2]BF 4 have also been prepared. The complexes have been characterised by 1H and 13C{1H} NMR and IR spectroscopy, electrospray mass spectrometry and microanalysis. The crystal structure of the anion exchanged [Rh(CO){Ph2Sb(CH2)3SbPh 2}2]PF6·3/4CH2Cl2 is also described. The methyl-substituted distibine complexes are less stable than the complexes of Ph2Sb(CH2)3SbPh 2, with C-Sb fission occurring in some of the complexes of the former. The salts [Rh(CO){Ph2Sb(CH2)3SbPh 2}2]PF6 and [Rh{Ph2Sb(CH 2)3SbPh2}2]BF4 undergo oxidative addition with Br2 to give the known [RhBr 2{Ph2Sb(CH2)3SbPh2} 2]+, while using HCl gives the same hydride complex from both precursors, which is tentatively assigned as [RhHCl2{Ph 2Sb(CH2)3SbPh2}]. An unexpected further Rh(iii) product from this reaction, trans-[RhCl2{Ph 2Sb(CH2)3SbPh2}{PhClSb(CH 2)3SbClPh}]Cl, was identified by a crystal structure analysis and represents the first structurally characterised example of a chlorostibine coordinated to a metal. [Rh{Ph2Sb(CH2) 3SbPh2}2]BF4 reacts with CO to give [Rh(CO){Ph2Sb(CH2)3SbPh2} 2]BF4 initially, and upon further exposure this species undergoes further reversible carbonylation to give a cis-dicarbonyl species thought to be [Rh(CO)2{Ph2Sb(CH2) 3SbPh2}{κ1Sb-Ph2Sb(CH 2)3SbPh2}]BF4 which converts back to the monocarbonyl complex when the CO atmosphere is replaced with N2.
