With heavier halides, the coordination quantities are lessen. The opposite trihalides are dimeric or polymeric with tetrahedral 4-coordinate aluminium centers.[g] Aluminium trichloride (AlCl3) incorporates a layered polymeric structure under its melting point of 192.4 °C (378 °F) but transforms on melting to Al2Cl6 dimers. At bigger temperatures People increasingly dissociate into tri... https://shedsandgarages23344.eedblog.com/37691750/5-tips-about-aluminium-greenhouse-you-can-use-today
