Lanthanide complexes arsine oxides

Studies of the complex chemistry of the tervalent lanthanides show that coordination numbers higher than six are common, for example in the tetrakistropolonates 79), the complexes of the perchlorates with N,N-dimethylacetamide (DMA) (77) or octamethylpyrophosphoramide 61), of the iodides with N,IV-dimethylformamide (DMF) (76), the nitrates with triphenylphosphine (or arsine) oxide 46), and the -diketone... 

CCC (1987) contains a section on sulfoxides, amide, amine oxides, and related ligands that have sections on phosphine oxides and arsine oxides.159 Phosphine and arsine oxide complexes of yttrium and the lanthanides were highlighted in CCC (1987).1 Scandium and yttrium phosphine oxide complexes have been reinvestigated and characterized by multinuclear NMR and X-ray...
