The reaction of - with bidentate diphosphines P-P give the cationic complexes +>- A = BPh4 or PF6> in good yield.An analogous complex was prepared with Me2PCH2CH2NMe(CH2)3NMeCH2CH2PMe2 whereas the bulky Pri2PCH2CH2PPri2 (dippe) gave a binuclear complex which on the basis of 31P NMR spectroscopy has bridging chloride groups.An X-ray crystal structure of revealed a distorted trans-octahedral geometry about technetium with an exceptionally long Tc=N bond distance of 1.853(6) Angstroem.Reaction of - with 2,2'-bipyridyl (bipy) in ethanol gives 2.An X-ray crystal structure revealed a cis-octahedral structure for the nitrido-cation with the novel tetrahedral tetrabromotechnetate(II) dianion.
