Crystal structure of a DNA duplex containing four Ag(i) ions in consecutive dinuclear Ag(i)-mediated base pairs: 4-thiothymine–2Ag(i)–4-thiothymine

Abstract

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.
