Abstract: The title complex, [-2-amino-N,N'-bis(3-hydroxysalicylidene)benzylamine(4-)]bis(pentane-2,4-dionato)(pyridine)zinc(II)uranium(IV) tetrahydrofuran solvate, [UZn(C₂₁H₁₄N₂O₄)(C₅H₇O₂)₂(C₅H₅N)]·C₄H₈O, is a novel example of a dinuclear complex including one 3d and one 5f metal ions. The U atom is located in the O₄ site of the Schiff base ligand 2-amino-N,N'-bis(3-hydroxysalicylidene)benzylamine (L¹) and is further bound to two acetylacetonate groups, which gives an octacoordinated dodecahedral environment. The Zn atom is in the inner N₂O₂ site. Its bonding to an axial pyridine molecule results in a pentacoordinated square-pyramidal environment.
