With heavier halides, the coordination figures are lower. The other trihalides are dimeric or polymeric with tetrahedral 4-coordinate aluminium facilities.[g] Aluminium trichloride (AlCl3) features a layered polymeric framework underneath its melting point of 192.4 °C (378 °F) but transforms on melting to Al2Cl6 dimers. At bigger temperatures those progressively dissociate into trigonal https://shedsandgarages23445.actoblog.com/38121423/how-much-you-need-to-expect-you-ll-pay-for-a-good-sheds-and-garages
