With heavier halides, the coordination numbers are lessen. One other trihalides are dimeric or polymeric with tetrahedral 4-coordinate aluminium centers.[g] Aluminium trichloride (AlCl3) contains a layered polymeric composition below its melting level of 192.four °C (378 °File) but transforms on melting to Al2Cl6 dimers. At higher temperatures those more and more dissociate https://jaredlcsma.wssblogs.com/37282561/a-secret-weapon-for-aluminium-greenhouse
