The title complex, [Y-2(C6H7)(4)(C3H7O)(2)], is a centrosymmetric dimer bridged through the O atoms of the isopropoxide ligands. The Y2O2 unit is planar and the geometry around the eight-coordinate Y atom is distorted pseudo-tetrahedral. The Y-O distances are 2.2228 (19) and 2.2432 (19) Angstrom, and the O-Y-O angle is 74.86 (7)degrees.
