Symmetrical dinuclear complexes with high DNA affinity based on [Ru(dpq)2(phen)]2+†
Abstract
Symmetrical homometallic dinuclear complexes of the type [{Ru(dpq)2}2(phen–SOS–phen)]4+, with a flexible 2-mercaptoethyl ether linker joining the two [Ru(dpq)2(phen)]2+-based sub-units, have DNA dissociation constants (Kd) in the nM range.
