Aluminium monofluoride, also known as fluoridoaluminium, is the chemical compound with the formula AlF. This elusive species is formed by the reaction between aluminium trifluoride and metallic aluminium at elevated temperatures but quickly reverts to the reactants when cooled.{{cite journal | last1 = Dyke | first1 = C.Kirby | last2 = Morris | first2 = B.W.J.Gravenor | year = 1984 | title = A study of aluminium monofluoride and aluminium trifluoride by high-temperature photoelectron spectroscopy | journal = Chemical Physics | volume = 88 | issue = 2| page = 289 | doi = 10.1016/0301-0104(84)85286-6 |bibcode = 1984CP.....88..289D }} Clusters derived from related aluminium(I) halides can be stabilized using specialized ligands.{{cite journal | last1 = Dohmeier | first1 = C. | last2 = Loos | first2 = D. | last3 = Schnöckel | first3 = H. | year = 1996 | title = Aluminum(I) and Gallium(I) Compounds: Syntheses, Structures, and Reactions | journal = Angewandte Chemie International Edition in English | volume = 35 | issue = 2| pages = 129–149 | doi = 10.1002/anie.199601291 }}
