1Rare Neutral Diphosphine Complexes of Scandium(III) and Yttrium(III) Halides.

Carravetta M1, Concistre M1, Levason W1, Reid G1, Zhang W1.

Inorg Chem. 2016 Dec 19;55(24):12890-12896. Epub 2016 Nov 23.

Reaction of Me2PCH2CH2PMe2 or o-C6H4(PMe2)2 (L-L) with a suspension of ScI3 or YI3 in MeCN solution under rigorously anhydrous and oxygen-free conditions produced the highly unusual complexes [ScI3(L-L)2], [YI3(Me2PCH2CH2PMe2)2], and [YI3{o-C6H4(PMe2)2}2MeCN]. X-ray crystal structures reveal that the scandium complexes adopt seven-coordinate, pentagonal-bipyramidal geometries with chelating diphosphines, while the eight-coordinate [YI3{o-C6H4(PMe2)2}2MeCN] is dodecahedral.
