The crystal structure of (NBU,)~[TC(NCS)~] shows near-perfect octahedral geomery and establishes that thiocyanate is N-bonded with a n average Tc-N-C angle of 173(2)". * D. AQUA,HALIDE,AND RELATED DIMERIC COMPLEXES No mononuclear Tc(II1) halide is known. 5 bromo ligands, respectively. These results indicate a low affinity of Tc(II1) for halide and the possibility of preparing [ T c ( O H ~ ) ~in] ~a+weakly coordinating aqueous medium (2311, The stability of the mixed-valence [ T C " ' ~ ' ' ~ C ~ ~ ] ~ and the apparent inability to prepare [ T c " ' ~ C ~ ~were I ~ - a puzzle for a number of years in view of the stability of [Re2C1,12- and the only fleeting existence of [RezC1813-(159).
These complexes are generally referred to as BATOs (boronic acid udducts of technetium dioximes) and have the general structure [TcX(dioximeH),(dioxime)BR'](X = C1, Br; R' = alkyl) shown in 18. At the uncapped end the three dioxime oxygen atoms are intramolecularly bonded to two bridging protons. The formation of BATOs from TcO,- and Sn2+ proceeds via several intermediates, including an Sn-monocapped [Tc"'(dioximeH),(p-OH)SnC13],which undergoes acid decomposition to give 34 JOHN BALDAS R the uncapped [Tc"'X(dioximeH),(dioximeHz)] complex.
COMPLEXES WITH SCHIFF BASEAND OTHER NITROGEN LIGANDS A number of Schiff base complexes have been prepared by substitution of [TcCl6I2-or [TcCI,(PP~,)~] (376,269). 7 BM, consistent with a d3 configuration (379). The reaction of [TcOCl,]- with aromatic amines and dppe in refluxing alcohols gives the purple air-stable imido complexes [TcCl(NAr)(dppe),]+ in good yield. Paramagnetism is evident in the broadened NMR spectra. The shows that the hycrystal structure of tr~ns-[TcCl(NNMe~)(dppe)~IPF~ drazido(2-) ligand is bonded as a linear four-electron donor (278).
