Stereochemistry and chiroptical properties of bimetallic single helicates of hexapyrrole-α, ω-dicarbaldimines with high diastereoselectivity

Bimetallic complexes of hexapyrrole-α,ω-dicarbaldimines consisting of a pair of four-coordinate metal sites adopt a helical closed C2-symmetric form or sigmoidal open forms depending on whether the...
