Abstract

A thorough examination of the disassembly of bimetallic triple-stranded lanthanide helicates [Ln2(Li)3]6+ (stoichiometry S = m/n = 2/3 = 0.67, global complexity GC = m + n = 2 + 3 = 5) in excess of metals shows the competitive formation of standard linear bimetallic complexes [Ln2(Li)2]6+ (S = 1.0, GC = 4), and circular trimetallic single-stranded helicates [Ln3(Li)3]9+ (S = 1.0, GC = 6).
