Crystal structures and spectroscopy studies of lanthanide complexes with l-proline [Ln(l-proH)2(H O) 2 5]Cl3 (Ln = Ho, Dy)

Abstract

The isomorphic crystals of dysprosium(III) and holmium(III) complexes with proline of formula [Ln(C5H9NO2)2(H2O)5]Cl 3 (compound I holmium; compound II, dysprosium) were synthesized and characterized by crystal structures and spectroscopic properties. The space group is P21 with lattice parameters: I a = 11.968(2), b = 11.030(2), c = 8.309(2) ??, ? = 106.97(3)?; II a = 11.968(4), b = 11.038(4), c = 8.302(2) ??, ? = 107.00(3)?.
