Abstact

Herein, we determined a high-resolution crystal structure of a B-form DNA duplex containing consecutive dinuclear metal ion-mediated base pairs, namely, 4-thiothymine-2Ag(i)-4-thiothymine (S-2Ag(i)-S), and four Ag(i) ions form a rectangular network and the distances between the Ag(i) ions are 2.8-3.2 Å, which may indicate the existence of metallophilic attractions.
