The crystal structures of [Co(NH 3 ) 6 ][Bi(Guo1,2′,3′H −3 ) 2 ] · 9 H 2 O ( 1 ), Na[Sb(Ado2′,3′H −2 ) 2 ] · H 2 O ( 2 ), and Na 2 [Bi(Ado2′,3′H −2 )(Ado2′,3′,5′H −3 )] · 13.5 H 2 O ( 3 ) were determined from single‐crystal X‐ray diffraction data (Guo = guanosine, Ado = Adenosine). The chelate complex anions of all structures consist of a bismuth(III) or antimony(III) center which is coordinated by the 1,2‐diolato group of the ribofuranosyl moiety of the nucleosides. In 1 , two guanine moieties belonging to different complexes are linked by two hydrogen bonds of the type N2–H···N3. 13 C NMR data obtained from the mother liquors show a coordination‐induced shift for the coordinating alkoxido groups of guanosine and adenosine as well as inosine.
