A new series of solids with ligand-unsupported Au(I) chains with short Auâ¯Au contacts were synthesized; as Ag compounds with the same structure are known, the new phases now allow unbiased comparison of Agâ¯Ag and Auâ¯Au metallophilic bonds not supported by bridging ligands, which shows the latter to be consistently shorter by 0.03â0.04 Ã
