Mixed carboxylate complexes of cerium(III) and yttrium(III), [Ce2(OAc)4(salH)2(OH2)4]A?4HOAc and [Y2(OAc)4(salH)2(OH2)4]A?2 H2sal (HOAc, H2sal a? acetic, salicylic acids) have been structurally characterized as tetrakis(acetic) and bis(salicylic) acid solvates, respectively. The dinuclear complex components take an identical form: [(OAc-O,O )(H2O)2Ln(O,I?-O -OAc)2(O-Hsal-O )2Ln(OH2)2(O,O - OAc)], with bridging pairs of acetate and salicylate ligands. The solvating acid molecules are closely and elegantly associated with the dinuclear complex via hydrogen bonding, these aggregates in turn being held together in the lattice by interactions between water molecule hydrogen atoms and neighboring carboxylate oxygen atoms.
