Crystal structures. (a) Line drawing of Λ-(I), Λ-[Ru(phen)2(qdppz)]2+; (b) thermal ellipsoid plot of one cation from the small-molecule structure of rac-(I); and (c) overall view of the asymmetric unit of the structure reported here with the DNA sequence shown below. A single strand of the sequence d((G3T2A)2G3T3G3) is found assembled with three K+ ions and a single molecule of Λ-(I). The Protein Data Bank (PDB) accession code is 7OTB. The color code for residues throughout are as follows: guanine—green, thymine—blue, and adenine—red. Ruthenium complexes are colored in the following scheme; teal for ruthenium, pink for carbon, and dark blue and white for nitrogen and hydrogen, respectively. The complete numbering scheme for Λ-(I) is shown in Figure S3.
