The crystal structure of the title compound was determined by the X-ray diffraction method. The crystal system is triclinic, space group P1 with Z = 2. The unit-cell parameters are: a = 7.4417(8)Å, b = 10.7676(12)Å, c = 11.3576(13)Å, with α = 108.599(2)°, β = 91.892(2)° and γ = 92.532(2)°. The final R value is 0.0561 for 3165 reflections measured. The geometry for the complex ion corresponds to the characteristic “three-legged piano stool” configuration.
