Abstract

New purinium, adeninium and guaninium fluoroaluminates, [Hpur] ₂·(AlF₅), [Hade]₃·(AlF ₆)·6.5H₂O and [Hguan]₃·(Al ₃F₁₂), are synthesized by microwave heating assisted hydrothermal synthesis at 120 °C or 190 °C. The crystallisation is difficult; all crystals of [Hpur]₂·(AlF₅) and [Hade]₃·(AlF₆)·6.5H₂O are very small while only a microcrystalline powder of [Hguan]₃· (Al₃F₁₂) is obtained. The structures are determined from crystal ([Hpur]₂·(AlF₅) and [Hade] ₃·(AlF₆)·6.5H₂O) or powder ([Hguan]₃·(Al₃F₁₂)) X-ray diffraction data. In [Hpur]₂·(AlF₅), trans-chains of corner sharing octahedra lie along the c axis of the tetragonal cell (a = 18.997(2) , c = 3.6980(4) , P4/n, Z = 4). In [Hade]₃·(AlF ₆)·6.5H₂O, the octahedral AlF₆ units lie in (010) planes with water molecules. In [Hguan]₃·(Al ₃F₁₂), trimers of corner sharing octahedra are associated by opposite vertices along the c axis of the trigonal cell (a = 14.254(1) , c = 3.629(1) , P3, Z = 1). The purine, adenine and guanine amines are monoprotonated and lie between the preceding chains or layers. Hydrogen bonds between fluoride ions and amine groups of organic cations or, eventually, water molecules ensure the stability of the structures, together with N-H⋯O intermolecular bonds between guaninium cations in [Hguan]₃·(Al ₃F₁₂). The N(7)H-amino and N(9)H-amino tautomeric forms of [Hade]⁺ are simultaneously found in [Hade]₃· (AlF₆)·6.5H₂O.
