With heavier halides, the coordination figures are reduce. The opposite trihalides are dimeric or polymeric with tetrahedral four-coordinate aluminium facilities.[g] Aluminium trichloride (AlCl3) has a layered polymeric framework below its melting place of 192.4 °C (378 °F) but transforms on melting to Al2Cl6 dimers.
