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.
