Ferrocene−Bis(thymine/uracil) Conjugates: Base Pairing Directed, Spacer Dependent Self-Assembly and Supramolecular Packing

Abstract

X-ray crystallographic studies of methylene linked Ferrocene-bis(thymine/uracil) conjugates Fc(T:T)M and Fc(U:U)M reveal base dependent 2-D supramolecular assemblies generated via wobble self-pairing for bis-thymine and reverse wobble self-pairing for bis-uracil conjugates, differing in architecture from the corresponding butylene spacer linked conjugates
