Abstract: | Alkylammonium Hexachlorometallates. I. Crystallization Properties and Crystal Structure of Diethylenetriammonium Hexachlororhodate, H3N(CH2)2NH2(CH2)2NH3]RhCl6] The reaction of RhCl3 · 3H2O with diethylenetriamine in 12 m hydrochloric acid yielded diethylenetriammonium hexachlororhodate H3N(CH2)2NH2(CH2)2NH3]RhCl6] ( 1 ). Dark red single crystals of the compound were grown under hydrothermal conditions at a temperature interval of 180°C to 125°C in closed glass ampoules over several weeks (space group C2/c, a = 30.956(4) Å, b = 7.371(2) Å, c = 12.9736(15) Å, β = 113.787(11)°, Z = 8, 2385 reflections with I > 0, wR2(obs.) = 0.0279, R1(I > 2σ(I)) = 0.0271). The crystal structure is determined by a complex framework of hydrogen bonds between the hexachlororhodate anions and the diethylenetriammonium cations. |
