摘要:
Controlled hydrolysis of ScCl3(THF)(3) results in the replacement of one tetrahydrofuran molecule to provide colourless crystals of ScCl3(THF)(2)(H2O). An X-ray structure determination of this 'mixed' solvate shows discrete six co-ordinate scandium atoms bonded to three chlorine atoms and three O-donor solvent molecules in a mer-octahedral arrangement.
