Three new monodimensional hybrid metal (Ti, In, Al) fluorides are synthesized with ethylenediamine (en) as a templating agent in solvothermal conditions assisted by microwave heating. All structures involve inorganic chains built up from TiO2F4 octahedra connected by two opposite O2− vertices in [H2en]·(TiOF4) (I), from InF6(H2O) pentagonal bipyramids linked by F–F edges in [H2en]·(InF4(H2O))2·H2O (II) and from (Al7F30)9− polyanions sharing two opposite AlF6 octahedra in [H2en]3·(Al6F24) (III). I is tetragonal, P4/ncc, a = 12.761(3) Å, c = 8.041(3) Å; II is orthorhombic, F2dd, a = 6.904(5) Å, b = 16.559(5) Å, c = 19.777(4) Å and III is monoclinic, P21/n, a = 9.387(2) Å, b = 6.710(2) Å, c = 21.513(6) Å, β = 97.18(3)°.
