N2 - Six new adducts of the form AgX:PPh3:H2C(pz(x))(2) (1:1:1) (H2C(pz(x))(2) = H2C(pz)(2) = bis(pyrazolyl)methane or H2C(pz(Me2))(2) = bis(3,5-dimethylpyrazolyl)methane; X = ClO4, NO3, SO3CF3) have been synthesized and characterized by analytical, spectroscopic (IR, far-IR, H-1 and P-31 NMR) and two of them also by single crystal X-ray diffraction studies for comparison with counterpart adducts with 2,2'-bipyridyl ('bpy') derivatives reported in a previous paper, the bpy-derived ligands forming five-membered chelate rings, while the present H2C(pz(x))(2) should, potentially, form six-membered rings. Such is the case, the two adducts exhibiting quasi-planar N2AgP coordination environments, perturbed by the approach of the oxyanion, unidentate in the case of the perchlorate but, in the case of the nitrate, an interesting disordered aggregate of differing unidentate modes.
