Silver(I)-organophosphane complexes of the dihydridobis(3-nitro-1,2,4-triazolyl)borate ligand.: X-ray crystal structure of {[H2B(tzNO2)2]Ag[P(m-tolyl)3]2} with the scorpionate ligand co-ordinated in an unidentate κ1-N fashion

New silver(I) complexes have been synthesised from the reaction of AgNO3, monodentate PR3 (PR3 = P(o-tolyl)(3), P(m-tolyl)(3), P(p-tolyl)(3), P(p-C6H4F), SeP(C6H5)(3)) or bidentate tertiary (dppe = bis(diphenylpliosphane)ethane, dppf = 1,1'-bis(diphenylphosphane)ferrocene) phosphanes and potassium d ihydrobis(3-nitro- 1,2,4-triazolyl) borate, K[H2B(tz(NO2))(2)]. These compounds have been characterized by elemental analyses, FT-IR, ESI-MS and multinuclear (H-1 and P-31) NMIR. spectral data. The adduct {[H2B(tz(NO2))(2)]Ag[P(m-tolyl)(3)](2)} has been characterized by single crystal X-ray studies. In the former, the H2B( tz(NO2))(2) acts as a monodentate ligand utilizing the coordinating capability of only one of the additional (exo-) ring nitrogens to complete the coordination array about the silver atom.
