Abstract
Tetrafluoroborate salts of cationic ruthenium complexes [Ru(κ3-tpy)(EPh3)2Cl]+ (tpy=2,2′:6′,2″-terpyridine; E=P, 1 or As, 2) containing both the group 15 donor ligands and tpy and their representative substitution products are reported. Weak interaction {C–H⋯X (X=Cl, F and π) and π–π interaction} studies revealed the presence of a double helical motif in complex 1, while the complex 2 assumes a single helical motif. Intercalative mode of interaction of the complexes 1 and 2 with calf thymus DNA (ctDNA) has been supported by absorption titration studies.
