Lanthanide, main group, and transition metal ion templates provide different polynuclear cages from [M(L)] (M=Ni, Mn; (L) 2− =CH 2 [CH 2 N=C(CH 3 )COO − ] 2 ). Templating with lanthanum results in a 12‐coordinate La III ion encapsulated by six [Ni(L)] units, whereas with sodium four Na + ions are trapped inside a tricapped trigonal prismatic [{Ni(L)} 9 ] cage. With manganese, an octahedrally coordinated Mn II ion is surrounded by six [Mn(L)] fragments in a twisted trigonal‐prismatic configuration (see picture).
