Stepwise and reversible deprotonation of organometallic glyoxime complexes of iridium has been achieved. The juggling of the proton beanbag yielded coordination compounds with a variety of structural motifs in their crystals such as one‐dimensional infinite chains, polymeric hexagonal open channels, and a discrete dinuclear complex. Formation of the diverse supramolecular structures is ascribed to the diprotic nature of the glyoxime ligand, which offers sites for hydrogen bonding in the second coordination sphere as well as coordination to the metal centers.
