The preparation of a series of mononuclear mixed-ligand silver(I) nitrate complexes of the general formula [Ag(PPh3)2(thione)n] [NO3] (n = 1,2; thione = pyridine-2-thione ( py2tH), pyrimidine-2-thione (pymtH), 4-methylpyrimidine-2-thione (MepymtH), 4-aminopyrimidine-2-thione (NH2pymtH), 4-hydroxypyrimidine-2-thione (OHpymtH), quinoline-2-thione (quintH), benz-1,3-thiazolidine-2-thione (btzdtH), and benz-1,3-oxazoline-2-thione (boztH) ) is described and their solid state and solution spectroscopic data reported. The crystal structure of [Ag(PPh3)2(boztH)2] [NO3] is also reported and discussed with respect to analogous complexes. The coordination geometry about the silver atom is distorted tetrahedral with mean Ag-S and Ag-P bond lengths of 2.67 and 2.49 A respectively and a nitrate ion forming hydrogen bridge with one of the thione NH-groups of the complex ion. The inequality of the Ag-S bonds together with the bulk of the thione account for the observed solution 31P NMR spectra.
