(AdeH2) SbCl_5 · H_2O (1), (AdeH) _2SbCl_5 · H2O (2) (Ade: Adenine) and (AdeH) [Sb (pdta)] · 2H_2O (H_4pdta: Propylenediaminetetraacetic acid ) Crystal structure. In the compound (1), its molecular structure consists of a dihydroadenine cation, SbCl52- and water of crystallization. Anions in Sb (Ⅲ) and chlorine atoms form distorted octahedron coordination, and to form a common vertex chain structure. In the compound (2) contains a hydrogen adenine cation, SbCl52- and water of crystallization, Sb (Ⅲ) is also coordinated with the chlorine atoms to form a distorted octahedral structure, but the formation of dimer dimer. In the compound (3), the structure includes a hydrogen adenine cation, [Sb (pdta)] -, and two crystal water. In the above three crystal structures, the water molecules all form hydrogen bonds with the anions and cations. A brief discussion of the possibility of base coordination between Sb (III) and a nucleic acid.
