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.
Notes:
Bei der Reaktion von RhCl3 · 3H2O mit Diethylentriamin in 12molarer Salzsäure erhält man Diethylentriammoniumhexachlororhodat [H3N(CH2)2NH2(CH2)2NH3][RhCl6] (1). Dunkelrote Einkristalle wurden in der Mutterlauge unter hydrothermalen Bedingungen innerhalb einiger Wochen in einem Temperaturintervall von 180°C-125°C in verschlossenen Glasampullen gezüchtet (Raumgruppe C2/c, a = 30,956(4) Å, b = 7,371(2) Å, c = 12,9736(15) Å, β = 113,787(11)°, Z = 8, 2385 Reflexe mit I 〉 0, wR2(obs.) = 0,0279, R1(I 〉 2σ(I)) = 0,0271). Die Struktur wird durch ein komplexes Netzwerk von Wasserstoffbrückenbindungen zwischen den Hexachlororhodat-Anionen und den Diethylentriammonium-Kationen bestimmt.
