Abstract
For the first time, the concept of supramolecular synthons was applied to giant rigid superspheres based on pentaphosphaferrocene [(CpFe)-Fe-R(eta(5)-P-5)] (R = Me, Et) and Cu(I) halides, which reach 2.1-3.0 nm in diameter. Two supramolecular synthons, sigma-pi and pi-pi, are discovered based on halogen center dot center dot Cp-R and Cp*center dot center dot center dot Cp* specific interactions, respectively. The geometry of the synthons is reproducible in a series of crystal structures of various supramolecules. The sigma-pi synthon alone is realized more frequently for Br-containing superspheres. A combination of the sigma-pi and pi-pi synthons is more typical for Cl-containing supramolecules. Each supramolecule can bear up to nine synthons to give mostly 2D and 3D architectures.
