Front Cover: Preferential Formation of Three-layered Host–Guest Complexes of a Planar Dinuclear Metallohost with Alkali Metal Ions (Chem. Eur. J. 71/2024)

Abstract

Three-layered host–guest complexes were preferentially formed by complexation of a macrocyclic dinickel metallohost with 2/3 equiv of larger alkali metal ions (K⁺, Rb⁺, Cs⁺). Spectroscopic and theoretical investigations clearly demonstrated their unique three-layered structure in which the three metallohost molecules are stacked in a parallel fashion and the two nickel complex moieties in each of the metallohosts are oppositely curved.
