“…These examples involve situations where one or more misassigned atom(s) results in an erroneous charge balance which is then satisfied by invoking coordinated H 3 O + . The CCDC identifiers for these structures are SINZAS and QOZCOA . Details of the former are given below, while the latter is given in the Supporting Information (pages 39–40).…”

The evidence for the existence of metal complexes containing H 3 O + as a ligand in the solid state is examined. Each of the 68 examples in the Cambridge Structural Database in which H 3 O + is bound to a transition metal, lanthanoid, actinoid, or main group metal ion is detailed and critically appraised. It is concluded that none of the reported examples of complexes containing coordinated H 3 O + have been unequivocally characterized and that they result from either curation errors or misinterpretations of the crystallographic data. These conclusions are supported by computational techniques, which show that three purported H 3 O + complexes based on the 1,4,7,10,13,16,21,24-octaazabicyclo(8.8.8)hexacosane azacryptand skeleton are better described as aqua complexes, with protonation occurring at the amine ligand.
