Solid mixed-ligand complexes (MLC) formed by the action of pivalic acid on holmium, erbium, and ytterbium dipivaloylmethanates (MDpm{sub 3}) in hexane are isolated. It is established from the data of the elemental and spectroscopic analyses that erbium and ytterbium MLC are of composition MDpm{sub 3}{center_dot}HPiv, and, in the case of holmium, a mixture of the complexes of composition HoDpm{sub 3}{center_dot}HPiv and HoDpm{sub 2}{center_dot}HPiv forms. The isostructural single crystals of HoDpm{sub 3}{center_dot}HPiv and ErDpm{sub 3}{center_dot}HPiv are prepared, and the unit cell parameters are determined. An X-ray diffraction study is carried out for HoDpm{sub 3}{center_dot}HPiv, and the crystal structure of this compounds is determined.
