Mixed metal spirocyclic metallasiloxanes. Crystal structure of the pyridinolithium{bis(cyclodisiloxanediolato)bis(pyridino)cobalt}pyridinomanganese chloride compound [(Py2Li)-µ-{(Co(OsiPh2OsiPh2O)2·2Py}-µ-MnClPy]

Abstract

Treatment of a solution of the cobalt compound [Co(OSiPh₂OSiPh₂O)₂-µ-(LiTHF₂)₂]1 with manganese(II) chloride affords, after addition of pyridine, the first mixed transition metal metallasiloxane compound [(Py₂Li)-µ-([graphic omitted])₂-2Py)-µ-MnClPy]2; the results of single crystal X-ray diffraction and magnetochemical studies are reported, although disorder of the solution introduces some ambiguity into the data.
