Structure of a new compound synthesized by microwave heating : [H3N(CH2)6NH3)].AlF5

Abstract A new hybrid material was synthesized by the microwave route from a mixture of Al 2 O 3 /HF/1,6 diaminohexane/EtOH. The structure of the hybrid fluoroaluminate, determined by single crystal X-ray diffraction, reveals a [H 3 N(CH 2 ) 6 NH 3 ]·AlF 5 formulation and a monoclinic symmetry with the space group P2 1 , with a =7.898(1) A, b =5.514(1) A, c =12.672(3) A, β=103.69(2)°, V =536.2(2) A 3 and Z =2. The unit cell contains infinite inorganic chains of [AlF 6 ] corner-sharing octahedra, linked each other by hexanediammonium cations.
