from [Tc(OH2)(CO)3(PPh3)2]+ proceed under mild conditions and are generally almost quantitative. Some of the formed complexes are remarkably stable and inert, while others provide products with one labile ligand for further reactions. The derived complexes of the type [Tc(L)(CO)3(PPh3)2]+ and [Tc(L)2(CO)2(PPh3)2]+ represent an interesting opportunity for the development of 99mTc complexes with potential

The synthesis and characterization of new rhodium(III) complexes containing tellurium heterocyclic ligands are described. All complexes have the general formula of RhCl3L3 (where L = C4H8Te, C4H8TeI2, C4H8OTe, C5H8Te, C6H10Te, C8H5ClTe, C10H12Te and C16H10Cl2Te). Reactions of RhCl3L3 complexes with carbon monoxide are shown to replace only one cyclic telluride by carbon monoxide under mild conditions

been prepared by the reaction of 1,4-dibromobutane or 1,5-dibromopentane with potassium chalcogenides. The novelty of the route consists of the use of the hydrazine hydrate–KOH system for the reductive generation of potassium selenide, telluride, diselenide or ditelluride from elemental chalcogens.

The synthesis and spectroscopic characterization (IR, UV-vis 1H, 125Te and 195Pt NMR) of [ML2X2] and [RhL3Cl3] [L = H2)4; M = Pd or Pt; X = Cl, Br, or I] are reported. The [PtL2Cl2] complex is cis in the solid state but exists as a mixture of cis and trans isomers in solution. The other palladium and platinum complexes are trans isomers. Both mer and fac isomers are present in the rhodium complex in
