Assembly of a novel tripodal ligand, 1,3,5-tris(benzimidazol-2- ylmethyl)benzene (tbib), and triphenylphosphine with silver(I) and copper(I) salts gave the corresponding mononuclear complexes, which were characterized by electrospray mass spectrometry and ³¹P NMR spectroscopy. The structure of the silver(I) complex, [Ag(tbib)(PPh₃)]NO₃ · CH₃OH · H₂O, determined by X-ray crystallography, indicates that the silver(I) atom is coordinated by two nitrogen atoms of one tbib ligand and one phosphorus atom of triphenylphosphine. Another nitrogen atom of the tbib ligand is uncoordinated. The complex provides another example of a structurally characterized silver(I) complex with N₂P binding set.
