In the reaction of 3,3-bis(chloromercury)-2,4-pentanedione with TeCl4, Ph2TeCl2, or Ph3TeCl, the replacement of one HgCl group by a tellurium moiety gives Cl3Te(C5H6O2)HgCl*2C4H8O2 (I), Ph2Te(Cl)(C5H6O2)HgCl (II) and Ph3Te(C5H6O2)HgCl (III), respectively.The IR and 1H NMR data indicate that the Te is bonded to the C3 carbon of acetylacetone.In solution the compounds appear to ionize into Cl^- and an organometallic cation in which Hg seems to be involved in secondary interaction with the carbonyl groups; far IR and mass spectral data suggest that Hg-O interaction is significant even in solid state.
