A nanoscale turbine wheel is an apt description of the structure of the enantiomerically pure helicate [Ag 6 ( L2 ) 6 ] 6+ ( 1 ), which precipitates as PF 6 salt on mixing dissolved AgPF 6 with the ligand L2 (a bis‐bidentate ligand comprising two condensed α ‐pinene/bipyridine units linked by a xylylene bridge). The helicate has an outer diameter of about 3 nm and an inner diameter of 0.84 nm, and is a potential model for the study of stereospecific recognition processes.
