With heavier halides, the coordination quantities are decreased. Another trihalides are dimeric or polymeric with tetrahedral four-coordinate aluminium centers.[g] Aluminium trichloride (AlCl3) has a layered polymeric composition down below its melting place of 192.4 °C (378 °F) but transforms on melting to Al2Cl6 dimers. At larger temperatures those significantly dissociate into trig... https://claytonoeshu.anchor-blog.com/17898692/5-simple-statements-about-sheds-and-garages-explained
