摘要：

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 angstrom, which may indicate the existence of metallophilic attractions.
