corresponding Ti(IV) complex. The compounds [Li(py)4]+9a− and [Li(L)4]+(10b–d)− are obtained when (L)Li+1− are reacted with VCl3 and ScCl3. The X-ray structure analysis of the vanadium complex reveals a distorted tetrahedron of the anion [V(1a)4]− with two smaller and four larger CVC angles. The scandium compound [Li(dme)2+10c−] has a different structure: the distorted tetrahedron of the anion [Sc(1c)4]− contains
