With heavier halides, the coordination quantities are decrease. The other trihalides are dimeric or polymeric with tetrahedral 4-coordinate aluminium facilities.[g] Aluminium trichloride (AlCl3) contains a layered polymeric structure beneath its melting point of 192.4 °C (378 °File) but transforms on melting to Al2Cl6 dimers. At larger temperatures those ever more dissociate into https://aluminiumgreenhouse34567.bloguetechno.com/the-definitive-guide-to-aluminium-greenhouse-73088630
