D 2 ligands differ significantly from classical deuteride ligands in their deuterium quadrupole coupling constants (DQCCs), which were derived from 2 H‐ T 1 min measurements on polydeuteride complexes such as [pp 3 MD 2 ] and [pp 3 MD(D 2 )] + (M = Ru, Os; pp 3 = P(CH 2 CH 2 PPh 2 ) 3 ). The DQCC of the D 2 ligand is much lower than that of the classical deuteride ligand (DQCC values given in kHz below structures in picture).
