Abstract

The reaction of Ni(NO₃)₂·6H₂O with the thio-modified nucleoside 2'-deoxy-6-thioguanosine (d-tG, C₁₀H₁₃N₅O₃S) in methanol in a 1:1.3 stoichiometric ratio deposited the title compound, [Ni(d-tG)₃](NO₃)₂·2H₂O, as green crystals. Despite the <1:3 Ni-ligand ratio used in the synthesis, the deoxy-thioguanosine binds to form three N⁷,S⁶-coordinated five-membered chelate rings with individual Ni^II ions in mononuclear complexes rather than bridge metal centres into more extended oligomeric or polymeric structures.

期刊介绍： Acta Crystallographica Section C: Structural Chemistry is continuing its transition to a journal that publishes exciting science with structural content, in particular, important results relating to the chemical sciences. Section C is the journal of choice for the rapid publication of articles that highlight interesting research facilitated by the determination, calculation or analysis of structures of any type, other than macromolecular structures. Articles that emphasize the science and the outcomes that were enabled by the study are particularly welcomed. Authors are encouraged to include mainstream science in their papers, thereby producing manuscripts that are substantial scientific well-rounded contributions that appeal to a broad community of readers and increase the profile of the authors.
