Three new silver - tin complex salts with cis-1,2-bis(diphenylphosphino)ethylene have been synthesized. IR, ³¹P and ¹¹⁹Sn NMR and conductivity data are reported and discussed together with the X-ray crystal structure of one of them, [Ag(cdppet)₂][SnPh₃(NO)₃)₂]. The silver atom is distorted tetrahedrally surrounded by the four phosphorus atoms of the two cdppet ligands. The tin atom is in a slightly distorted trigonal bipyramidal geometry with the phenyl carbon atoms in the equatorial plane and two oxygen atoms from monodentate nitrate groups at the apices.
