Five new classes of crystalline, hydrocarbon-soluble group 3A metal (M) aryloxides are reported: , (1), , , Li, and 2> (Ar = C6H2Me-4-But2-2,6), ranging for (1) from M3+ being the 3d0, 4d0, to the 4fn (n = 0, 1, 2, 3, 9, 10, 11, or 13) ion; the title compound (1) ( M = Sc) has an approximately trigonal planar ScO3 skeleton (Sc 0.13 Angstroem out of the O3 plane) with av.Sc-O 1.869(15) Angstroem, av.O-Sc-O 119.5(2) deg, and av.Sc-O-C 168.4(5) deg.
