Abstract

The crystal structure of the title compound, [Rh(C6H19N4)Cl3]Cl·0.5H2O, is isotypic with the previously reported Ru analogue. The structure contains two crystallographically independent [Rh(Htren)Cl3]+ cations with a facial tridentate coordination of the monoprotonated tren ligand [tren = tris­(2-amino­eth­yl)amine], leading to an overall distorted octahedral coordination environment around the Rh(III) atom. In one of the two cations, the ethyl­ene groups of the two chelate rings as well as the non-coordinating ethyl­ammonium group are disordered over two sets of sites [0.579 (3):0.421 (3) occupancy ratio]. A series of N—H⋯Cl and O—H⋯Cl hydrogen bonds stabilizes the structure
