摘要：

A series of transition-metal ion cryptates of a tris(2-aminoethyl)amine-capped ligand showed enhanced stability of the +2 oxidation state compared with the tighter-capped sepulchrate ligand; crystal-structure determination showed that the manganese(II) cryptate was unprotonated while cryptates of the smaller, more highly Lewis acidic, cations could be obtained in a protonated form.
