Abstract: | Polyol Metal Complexes. 27. Bis-Diolato Antimonates(III ) with Guanosine as the Diol The complex anions of K3[SbIII(Guo1,2′,3′H?3)2] · 10 H2O ( 1 ) and [Co(NH3)6][SbIII(Guo1,2′,3′H?3)2] · 9 H2O ( 2 ) are four-coordinate homoleptic bis(diolato)antimonate(III ) species. The guanosine trianions act as carbohydrate ligands through their cis-furanoidic ribosyl moiety, thus forming no nucleobase–metal bonds. |
