    The hexamer duplex d(CGCGCA).d(TGCGCG) was crystallized with hexammineruthenium(III) ions in an orthorhombic space group; the crystals diffracted to 1.54 A resolution. Strong ion interactions with the adenine base induce a tautomeric shift from the amino to the imino form. Consequently, the A.T base pairing is disrupted. This structural study may be relevant to metal toxicity.
