The site symmetry of both the tris-oxalate and the tris-bipyridyl compexes is C3. Furthermore, the rather loose oxalate network is actively stabilized by the tris-bipyridyl complexes through electrostatic interactions from ir-overlap between oxalate and bipyridine along the trigonal axis. Selected crystallographic data including relevant bond lengths and angles are presented in Table 1. 

The structure of a further iridium bis(boryl) complex, the cationic species [(tbbpy)(cod)Ir(Bpin)2]+[OTf] (9.33), together with that of a related neutral tris(boryl) system (vide infra), has been reported as part of a study to elucidate the mechanism and intermediates of arene borylation chemistry [136]. 9.33 features an approximately octahedral coordination geometry with mutually cis pairs of bipyridyl, diene and Bpin ligands. The two Ir-B bond lengths [2.06(2) and 2.12(1) A] are effectively identical within the standard 3a limit.
