Not only AuI and HgII species but also CuI(SR) fragments can bind in a highly dissymmetrical fashion to symmetrical diimine chelate ligands; the 2 + 1 coordination arrangement observed for the metal in two complexes (tmphen)Cu(SR) (tmphen = 3,4,7,8-tetramethyl-1,10-phenanthroline) is characterised by obtuse angles α[N(1)–Cu–S] > 159° and by two very different distances Cu–N(1) and Cu–N(2).
