Silver (I) poly(1,2,4-triazolyl)borate complexes containing monodentate phosphane ligands

New silver (I) derivatives containing monodentate tertiary phosphanes and bis- or tris-(triazol-1-yl)borate ligands have been synthesized. [{H2B(tz)2}Ag(PR3)2] (R = Ph or m-tolyl) and [{HB(tz)3}Ag{P(o-tolyl)3}] are mononuclear arrays, the silver atoms lying in four-coordinate environments. In [{H2B(tz)2}Ag{P(p-tolyl)3}] one of the additional ('exo'-) ring nitrogens not only completes the four-coordinate array about the silver but also links successive asymmetric units into a single-stranded polymer.
