Abstract
Holmium β-diketonate complexes, Ho(hfa)3(tme), has been prepared and characterized by IR, TGA, MS, and single-crystal X-ray analyses. This complex is air- and moisture-stable and most importantly has good volatility and thermal stability. Holmium atom binds to nine oxygen atoms, contributed by six oxygen atoms of three hfa ligands and three oxygen atoms of the tme ligand. The coordination polyhedron of Ho can be described as a distorted tricapped trigonal prism. Crystal data for Ho(hfa)3(tme); orthorhombic P212121, a = 15.415(4), b = 13.17(2), c = 17.291(3) A, V = 3496(1) A3.
