Aluminum chloride (AlCl₃) is a compound of aluminium and chlorine. The solid has a low melting and boiling point, and is covalently bonded. It sublimes at 178 °C. Molten AlCl3 conducts electricity poorly,[1] unlike more ionic halides such as sodium chloride. It exists in the solid state as a six-coordinate layer lattice.

Benzotrichloride, also known as trichlorotoluene is an organic compound with the formula C₆H₅CCl₃. It is principally used as an intermediate in the preparation of other chemical products such as dyes.

Nitrogen trichloride, also known as trichloramine, trichlorine nitride is the chemical compound with the formula NCl₃. This yellow, oily, pungent-smelling liquid is most commonly encountered as a byproduct of chemical reactions between ammonia-derivatives and chlorine (for example, in swimming pools between disinfecting chlorine and urea in urine from bathers).

Boron trichloride is a chemical compound with the formula BCl₃. This colorless gas is a valuable reagent in organic synthesis. It is also dangerously reactive.

Phosphorus trichloride is a chemical compound of phosphorus and chlorine, having chemical formula pcl₃. It is the most important of the three phosphorus chlorides. It is an important industrial chemical, being used for the manufacture of organophosphorus compounds for a wide variety of applications. It has a 31p nmr signal at around +220 ppm.

Titanium(III) chloride is the inorganic compound with the formula TiCl₃. At least four distinct species have this formula; additionally hydrated derivatives are known. TiCl₃ is one of the most common halides of titanium and is an important catalyst for the manufacture of polyolefins.

Vanadium trichloride is VCl₃. This purple salt is a common precursor to other vanadium(III) complexes. VCl₃ is paramagnetic and has two unpaired electrons.
