Abstract

Ten novel adducts of the form AgClO4:PR3:L (1:1:1) (R = Ph, cy, o-tolyl; L = 2,2-bipyridyl ('bpy'), 2,2-biquinoline ('bq'), bis(2-pyridyl)amine ('dpa'), bis(2-picolyl)amine ('dpca')) have been synthesized and characterized by analytical, spectroscopic (IR, far-IR, H-1 and P-31 NMR) and single crystal X-ray diffraction studies. The solid state molecular structures show that the complexes predominantly take the form [(R3P)AgL]X-+(-), with a trigonal PAgN2 Coordination environment, where the approach of the anion or the solvent may perturb the planarity of the silver environment. The ClO4 anion shows uni- or semi-bidentate coordination, except in the complexes AgClO4:PR3:dpca (1: 1: 1) (R = Ph and o-tolyl), where the anion remains uncoordinated and the dpca donor is a three-coordinate pincer-like ligand.
