Synthesis and structural characterization of adducts of silver(I) carboxylate salts AgX (X=CF3COO, CH3COO) with ER3 (E=P, As; R=Ph, cy, o-tolyl) and oligodentate aromatic bases derivative of 2,2′-bipyridyl, L, AgX:PR3:L (1:1:1)

Twenty-one adducts of the form AgX:ER3:L (1:1:1) (X=CF3COO (‘tfa’), CH3COO (‘ac’), E=P, As; R=Ph, cy, o-tolyl; L=2,2′-bipyridyl (‘bpy’)-based ligand) have been synthesized and characterized by analytical, spectroscopic (IR, far-IR, 1H, 19F and 31P NMR) and single crystal X-ray diffraction studies. The resulting complexes are predominantly of the form [(R3E)AgL]+X−, with a trigonal EAgN2 coordination environment, the planarity of which may be perturbed by the approach of anion or solvent.
