Rapid synthesis of hybrid fluorides by microwave heating

Two new series of organic–inorganic fluorides are synthesized by microwave heating. These compounds constitute probably the first new materials obtained by this way. The conditions of synthesis and several structural features of these hybrid materials together with the structure of the first member of the series, [H3N(CH2)6NH3]·AlF5, are reported. It crystallizes in the monoclinic system, space group P21, with the lattice parameters a = 7.894(2) Å, b = 5.507(1) Å, c = 12.658(2) Å, β = 103.67(1)°, V = 535(2) Å3, and Z = 2. Its structure consists of vertex-sharing infinite chains of AlF6 octahedra connected by diprotonated 1.6 diamines.
