Abstract
A five‐coordinate chloride ion is believed to template the assembly of a pentadecanuclear lanthanide complex of europium(III). This cluster (see picture) has been prepared by coordination of europium(III) perchlorate with tyrosine at about pH 6. Single crystal X‐ray analysis established an unprecedented structure in which 15 constituent europium(III) ions are organized into three parallel pentagonal layers.Keywords
