Abstract
A new route to synthetize the pentaerythrityl tetramine (tetra), C(CH 2NH 2) 4, is established with a good overall yield (75-80%) and four hybrid fluorides, templated by tetra, are synthetized by hydrothermal technique and microwave heating: cis-[H 4tetra] •(AlF 5) 2 (I), trans-[H 4tetra] •(AlF 5) 2 (II), [H 4tetra]•(AlF 6)•(Cl) (III) and (H 3O)•[H 4tetra] 2•(Ga(OH) 2F 4)•(GaF 6) 2•2H 2O (IV). Structural determinations are performed from single crystal X-ray diffraction data. Structures of I and II are built up from infinite (AlF5)2-∞ chains of corner sharing AlF 6 octahedra; the octahedra are cis-connected in I and trans-connected in II. III and IV are molecular phases and consist of isolated AlF 6 (III) or Ga(OH) 2F 4 and GaF 6 (IV) octahedra. Isolated chloride ions are found in III. Charge balance is ensured by tetraprotonated amine [H4tetra]4+ and the cohesion between inorganic and organic parts is due to hydrogen bonds.
