Nitrosyl and Thionitrosyl Complexes of Technetium and Rhenium and Their Reactions with Hydrotris(pyrazolyl)borates.

ABSTRACT: The very limited number of structurally known thionitrosyl complexes of technetium was increased by the synthesis of [Tc^II(NS)Cl₃(PPh₃)₂] (3) and [Tc^II(NS)Cl₃(PPh₃)(OPPh₃)] (4) and their reaction products with hydrotris(pyrazolyl)borates, {HB(pz^R)₃}^-. Similar reactions were conducted with [Tc^I(NO)Cl₂(PPh₃)₂(CH₃CN)] and related rhenium thionitrosyls. Remarkably, most such reactions result in a rapid cleavage of the boron-nitrogen bonds of the ligands and the formation of pyrazole complexes of the two group 7 metals. Only one compound with an intact {HB(pz^R)₃}^- ligand coul
