摘要:

通过模拟结构因子计算将[(C4H9)4N][Sc(NCS)6]•3.5H2O的空间群从正交晶系的Pcab修正为立方晶系的Pa3.将Sc(C17H13N2O2)3和[(H2O)10(OH)2Sc2](C6H5SO3)4•4H2O从P1修正为C2/c.还将[Sc(NO3)3(H2O)3]•18-Crown-6的Pna21修正为Pnma.

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.
