## Abstract We report the synthesis of three new complexes related to the achiral [Ru(tpm)(dppz)py]^2+^ cation (tpm=tripyridazole methane, dppz=dipyrido[3,2‐__a__:2′,3′‐__c__]phenazine, py=pyridine) that contain an additional single functional group on the monodentate ancillary pyridyl ligand. Comp
The NMR-derived structure of an achiral… ] complex bound to duplex DNA confirms that it intercalates from the minor groove as described in the Full Paper by J. A. Thomas et al. on page 2407 ff. The structure also explains why the nature and position of a single functional group acts as an on/off sw
## Abstract A novel polypyridine ligand, dipyrido[3,2‐__a:__2′,3′‐__c__]phenazine‐11‐carboxylic acid methyl ester (=dppz‐11‐CO~2~Me), and its ruthenium(II) complex, [Ru(bpy)~2~(dppz‐11‐CO~2~Me)]^2+^ (**1**), were synthesized and characterized. The binding properties of this complex to calf‐thymus D
