Abstract:

The space group of [(C4H9)4N]3[Sc(NCS)6]• 3.5 H2O is revised from orthorhombic Pbca to cubic Pa by solving the cubic structure from the structure factors that are simulated from the orthorhombic structure. The space groups of three other scandium(III) structures that were originally reported in lower- symmetry settings are revised to higher- symmetry centrosymmetric settings: Sc(PMBP)3(HPMBP=1- phenyl- 3- methyl- 4- benzoylpyrazol- 5- one)from P to C 2/c, [(H2O)10(OH)2Sc2] (C6H5SO3)4•4H2O from P1 to C 2/c and [Sc(NO3)3(H2O)3]• 18- crown- 6 from Pna21 to Pnma.

Key words: Space group revision, Simulated structure factors, Scandium complexes
