Ortho‐carboxyphenyl‐dimethylarsine (CPDMA), ortho‐carboxpyhenyldiphenylarsine (CPDPA) and ortho‐carboxyphenyldi(p‐tolyl)arsine (CPDTA) react with mercury(II) halides to yield complexes having the formula HgX 2 L where X is Cl, Br or I and L is ligand. In view of infrared spectral data these complexes have been classified into two classes: (a) those in which the carboxyl group of the ligand remains free (ligand being monodentate), and (b) those in which the ligand acts as a bidentate group. The complex Hg(Cl 2 ) · CPDPA is the only example of type (a) and has been assigned a dimeric halogen bridged structure. The remaining eight complexes are assumed to be monomeric. A tetrahedral structure is proposed for all the nine complexes.
