Abstract 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 TiO 2 F 4 octahedra connected by two opposite O 2− vertices in [H 2 en ]·(TiOF 4 ) ( I ), from InF 6 (H 2 O) pentagonal bipyramids linked by F–F edges in [H 2 en ]·(InF 4 (H 2 O)) 2 ·H 2 O ( II ) and from (Al 7 F 30 ) 9− polyanions sharing two opposite AlF 6 octahedra in [H 2 en ] 3 ·(Al 6 F 24 ) ( III ). I is tetragonal, P 4/ ncc , a = 12.761(3) A, c = 8.041(3) A; II is orthorhombic, F 2 dd , a = 6.904(5) A, b = 16.559(5) A, c = 19.777(4) A and III is monoclinic, P 2 1 /n , a = 9.387(2) A, b = 6.710(2) A, c = 21.513(6) A, β = 97.18(3)°.
