All of the non-hydrogen atoms except the disordered 
solvent molecules were refined with anisotropic 
thermal displacement coefficients. 
Hydrogen atoms in the ligand were 
located geometrically, whereas those of solvent 
molecules were found on Fourier difference maps, 
and all the hydrogen atoms were refined in riding model.
