It belongs to monoclinic system with space group P21/n and crystal cell parameters:a=1.619 9（3）, b=0.680 5（1）, c=2.802 8（6） nm, β=94.15（3）°; V=3.082（1） nm 3, Z=4, Dc=1.289 g/cm3, Mr=589.22, μ（MoKα）=0.750 mm -1, F（000）=1 268. The structure was refined to R=0.057 8 and wR=0.158 1 for 4 447 observed reflections with I≥2σ（I）. The aquo complex is mononuclear with distorted square-pyramidal coordination.展开更多
