A surprising substitution of Cu by Li has been observed during the intercalation reaction of Cu 3 N with n ‐butyllithium, besides an expected incorporation of Li. The twofold coordinated Cu + ions are shifted into cuboctahedral cavities along with a reduction to Cu 0 (see picture). The chemical bonding of the compounds Li x Cu 3 N is analyzed in comparison to Cu 4 N on the basis of band‐structure calculations.
