Three new pyrazolated chalcogenoether ligated Rh(iii) half-sandwich complexes (1-3) were synthesised by the thermal reaction of chalcogenoether (S, Se and Te) substituted 1H-pyrazole ligands (L1-L3) and [(η5-C5Me5)RhCl]2 in methanol. The complexes were fully characterised by various spectroscopic techniques, and the molecular structures of complexes 1 and2 were also established through single crystal X-ray crystallographic analysis, which indicates a pseudo-octahedral half-sandwich piano-stool geometry around the rhodium metal. All three complexes were found to be thermally stable and insensitive towards air and moisture.

The reactions of 4-bromo-1-(2-chloroethyl)-1H-pyrazole prepared from 4-bromopyrazole with the in situ generated PhSNa, PhSeNa, Na(2)S and Na(2)Se have resulted in thio/selenoether ligands L1-L4 respectively. The complexes [PdL1/L2Cl(2)](1-2) and [PdL3/L4Cl]BF(4) (3-4) of these ligands have been synthesized by reacting them with [PdCl(2)(CH(3)CN)(2)] in CH(3)CN at 70 °C. The L1-L4 and their complexes (1-4) have been characterized with spectroscopic techniques viz.
