The presence of the alkoxylated intermediate formed by the addition of
alcohol to the cyano group has been confirmed by the isolation of the
dimeric copper(II) complex [CuCl2C8N2OH10](2), in which each five coo
rdinate copper atom is bound to two chlorine and two nitrogen atoms in
a square planar arrangement. In addition, there are weak axial intera
ctions between the copper and chlorine atoms which allow the formation
of a centrosymmetric dimer in which the copper atom has a square plan
ar coordination.
