Abstract
Scandium is probably the least-studied element in the fourth period. It is commonly grouped with yttrium and the lanthanides in Group 3 (IIIA), yet its atom (and ion) are considerably smaller than those of yttrium and lanthanum; it is however larger than Al3+ (with which it is often compared; ionic radius 0.5 Å in Group 13 (IIIB)). Table 1.1 compares the coordination numbers of scandium and lanthanides in a selection of coordination compounds with those of iron(III), a d5 ion with no ligand-field effects dictating the adoption of a particular coordination number.
