With heavier halides, the coordination figures are lower. The opposite trihalides are dimeric or polymeric with tetrahedral four-coordinate aluminium centers.[g] Aluminium trichloride (AlCl3) features a layered polymeric framework below its melting position of 192.four °C (378 °F) but transforms on melting to Al2Cl6 dimers. At better temperatures These significantly dissociate into tr... https://aluminium-greenhouse55667.rimmablog.com/36409286/helping-the-others-realize-the-advantages-of-sheds-and-garages
