molar ratio. The coordination ability of species 1, as well as that of bis[2-(3,5-dimethyl-1H-pyrazol-1-yl)ethyl]selane, [(3,5-dmpz)CH2CH2]2Se (3) toward several late transition metals (Pd, Au, Ag) was investigated by reacting the neutral ligands 1 and 3 with PdCl2, AuCl(tht) and AgOTf in a 1:1 molar ratio. The neutral ligands 1–3, as well as the gold(I), silver(I) and palladium(II) adducts [2-(Me2NCH2)C6H4][(3
