Exchange of cobalt(II) for copper(II) in a spirocyclic metallasiloxane compound; X-ray crystal structure of the spirocyclic copper(II)siloxane Cu(OSiPh2OSiPh2O)2-µ-(Lipy2)2(py = pyridine)

Abstract
Treatment of the spirocyclic cobalt compound C[graphic omitted])2-µ-(Litmeda)2(tmeda = tetramethylethylenediamine) with CuCl2 and pyridine afforded the analogous copper compound [graphic omitted])2-µ-(Lipy2)21 which has been characterised by X-ray crystallography.
