Structure of pentaamminechlororuthenium(III) bisulfate tetrahydrate

[RuCl(NH3)5](HSO4)2.4H2O, M(r) = 487.88, triclinic, P1, a = 10.0422 (5), b = 14.1044 (7), c = 6.3273 (6) A, alpha = 100.369 (5), beta = 98.655 (6), gamma = 81.354 (4) degree, V = 864.5 (3) A3, Z = 2, Dm = 1.86 (1), D chi = 1.874 g cm-3, lambda(MO K alpha) = 0.71073 A, mu = 13.3 cm-1, F(000) = 498, T = 296 (1) K, R = 0.025 for 4622 unique reflections with I greater than 3 sigma(I). The structure contains (NH3)5RuCl2+ cations, bisulfate anions and solvate water molecules all linked by an extensive hydrogen-bonding network. Each Ru ion is coordinated in a distorted octahedral fashion by five ammonia molecules and a chloride ion. The Ru--Cl distance [2.3742 (5) A] is typical for RuIII--Cl linkages. The Ru--NH3 distances span a narrow range [2.096 (2)-2.119 (2) A] and provide no evidence for a trans effect.
