Abstract
Ph3PO adducts with manganese(II) halides, viz. MnX2(OPPh3)2 (X = Cl or Br) were heated for 1 h and their X-band e.s.r. spectra recorded at r oom temperature. The chloride adduct, MnCl2(OPPh3)2 completely transfo rmed into the symmetrised product, [Mn(OPPh3)4] [MnCl4] at 175 and 225 -degrees-C. The bromide adduct, MnBr2(OPPh3)2, which is probably a mix ture of its nonionic and ionic forms at room temperature, showed hyper fine coupling in the g = 2.029 region.
