Abstract

The reaction of AgX (X = ClO4, NO3 or SO3CH3) acceptors with excesses of tris(pyrazol-1-yl)methane ligands L (L = CH(pz)(3) CH(4-MePZ)(3), CH(3,5-Me(2)pz)(3), CH(3,4,5-Me(3)pz)(3) or CH(3-MePZ)(2)(5-Mepz)) yields 1:1 [AgX(L)], 2:1 [Ag(L)(2)]X or 3:2 [(AgX)2(L)31 complexes. The ligand to metal ratio in all complexes is dependent on the number and disposition of the Me substituents on the azole ring of the neutral ligand and on the nature of the Ag(l) acceptor. All complexes have been characterized in the solid state as well as in solution (medium- and far-IR, H-1 and C-13 NMR and conductivity determinations) and the solid-state structures of [Ag(NO3){pz)(3)CH}]((infinity/infinity)) and [Ag{(3,5-Me(2)pz)(3)CH}(2)]NO3 determined by single crystal X-ray studies.
