In the laboratory BF3 reacted with AlCl3 gives BCl3 via halogen exchange.[2] BCl3 is a trigonal planar molecule like the other boron trihalides, and has a bond length of 175pm. It has a zero dipole moment because it is symmetric and therefore the dipole moments associated with the bonds cancel each other out.
