The new complexes indicated in the title have been synthesized, and the crystal and molecular structure of the neodymium(III) complex has been determined by the X-ray diffraction method.The crystal is monoclinic with the space group C2/c, Z=16, a=28.887(4), b=28.913(5), c=24.814(5) Angstroem, β=106.72(1) deg.The final R value for 7761 reflections is 0.066.The central neodymium(III) atom of the complex is octacoordinated and is in a dodecahedron geometry; three O,O'diisopropyl dithiophosphato ligands, chelating by both of the sulfur atoms, span the two m edges of a trapezium as well as one a edge of the other trapezium, and two oxygen atoms of both the benzamide ligate at both tips of the base edge of the latter trapezium.The solid and the acetonitrile solution of the europium(III) complex are orange in color, and they show a charge-transfer band in their near-ultraviolet absorption spectra.
