The centrosymmetric title tetramer, [U4(C2H3O2)4O10(H2O)4]·2CH4O, has a near planar core [maximum deviation from the least squares plane of 0.294 (6) Å]. It consists of two hexagonal–bipyramidally coordinated UVI atoms connected via μ2-O (acetate) and μ3-O (oxide) bridges in the equatorial plane to two pentagonal–bipyramidally coordinated UVI atoms. The equatorial plane of each UVI atom is completed by a bound water molecule, while the axial positions are occupied by uranyl (UO2)2+ O atoms. Multiple O—H...O hydrogen bonds are present, including a lattice methanol molecule bound to one of the pentagonal bipyramidal uranyl O atoms, as well as two different C_{1}^{1}(6) chains orginating from a donor water molecule, via a uranyl oxygen acceptor and an acetate acceptor on different, adjacent tetramers.
