The isomers α- and β-[L3RhHX2](L = tertiary phosphine or arsine. X = Cl or Br) are shown to have the same structures as the corresponding iridium complexes, i.e. a mer-configuration for the neutral ligands and hydride trans to halogen (α-form) or to the neutral ligand (β-form). The isomerisation β→α is enhanced by heat and light, but is inhibited in the presence of the free neutral ligand. indicating
