Abstract

Treatment of N-methyl substituted aminocryptand hosts with copper(II) generates monocopper(II)
cryptates where copper(II) coordinates an oxygen-centered species, formally H3O+, which is also
strongly hydrogen bonded to three aminocryptand N-methyl atoms via bonds which may best be
viewed as NHd+ · · ·Od− in consequence of charge transfer. The strength of this hydrogen bonding
precludes successful competition of another copper ion for the second coordination site thus
suppressing formation of any Cu–Cu bonded average-valent system.
