Abstract:
The solvate complexes that can be obtained by either dissolving metal iodides in N , N -dimethylformamide (DMF) or by synthesising them in DMF have the general composition [ M (DMF) x ]I y . DMF shows to behave as simple monodentate ligand with low sterical impact, so that x in the composition follows the radius of M y + . We present here the crystal structures of the alkaline earth and lanthanoid metal iodide complexes [Mg(DMF) 6 ]I 2 , [Ca(DMF) 6 ]I 2 , [Sr(DMF) 7 ]I 2 , [Ba(DMF) 8 ]I 2 , [La(DMF) 9 ]I 3 , [ Ln (DMF) 8 ]I 3 (isotypic series for Ln = Nd, Sm, Eu, Dy, Gd, Er, Yb and Lu) and for the tris-triiodide complex salt [Sc(DMF) 6 ](I 3 ) 3 . Their different crystal structure types can be compared on the basis of the packing topologies of the nearly spherical cationic entities which show simple sphere packing motifs.
