With heavier halides, the coordination numbers are reduced. The other trihalides are dimeric or polymeric with tetrahedral 4-coordinate aluminium centers.[g] Aluminium trichloride (AlCl3) includes a layered polymeric framework down below its melting issue of 192.4 °C (378 °F) but transforms on melting to Al2Cl6 dimers. At higher temperatures All those significantly dissociate https://augustjbpdr.popup-blog.com/36420622/a-secret-weapon-for-aluminium-greenhouse
