Abstract
The title compound, [Y2(C9H7O3)6(C10H8N2)2(H2O)2]·2C10H8N2, contains two eight-coordinated YIII ions, which are linked by two carboxylate groups from two 2-hydroxycinnamate anions, leading to a centrosymmetric dinuclear structure surrounded by solvent 4,4′-bipyridine molecules. It forms a three-dimensional framework connected by extensive O—H⋯O and O—H⋯N hydrogen-bonding interactions.
