Stimuli-induced reversible transformation between isomers of copper(I) clusters sharing an identical core.
The construction of reversible structural isomerization in atomically precise metal clusters remains a daunting challenge. Herein, we report the application of a bifunctionalized phosphine-alkyne ligand, (2-ethynylphenyl)diphenylphosphine (HL), to synthesize an octanuclear copper(I) cluster Cu8-1 [(Cu8(L)6(PF6)2], whic...
