New silver (I) derivatives containing monodentate tertiary phosphanes and anionic poly(triazol-1-yl)borate ligands have been prepared from the reaction of AgNO3 and PR3 (R = Ph, Bn, o-tolyl, m-tolyl, p-tolyl) and potassium dihydrobis(1,2,4-triazolyl)borate, K[H2B(tz)2], or potassium hydrotris(1,2,4-triazolyl)borate, K[HB(tz)3]; their solid state and solution properties have been investigated through
