N2  - Mercury(II) halide complexes of tris(4-methoxyphenyl)phosphine have been investigated by 31P and 199Hg n.m.r. spectroscopy of CH2Cl2 solutions. At room temperature the phosphine exchanges at an appreciable rate and halogen exchange is fast. At -50&#176;C both phosphine and halogen exchange are slow on the n.m.r. time scale and halogen redistribution reactions are observed.     Mercury(II) halide complexes with tributylphosphine selenide have been investigated by 31P, 199Hg and 77Se n.m.r. methods. This ligand is labile and exchanges rapidly on the n.m.r. time scale at room temperature, although the exchange can be slowed down at about -100&#176;C. Halogen exchange is also fast at room temperature.     Ligand exchange reactions between tributylphosphine and either tris(4-methoxyphenyl)phosphine or tributylphosphine selenide were investigated and redistribution reactions to give mixed ligand complexes were observed.
