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.
在此，我们确定了一种B型DNA双链体的高分辨率晶体结构，该双链体包含连续的双核金属离子介导的碱基对，即4-硫代胸腺嘧啶-2Ag(i)-4-硫代胸腺嘧啶（S-2Ag(i)-S），并且四个Ag(i)离子形成一个矩形网络，Ag(i)离子之间的距离为2.8 - 3.2 Å，这可能表明存在亲金属吸引力。
