A heterobimetallic zinc(II)/uranium(IV) complex with the Schiff base 2-amino-N,N′-bis­(3-hydroxy­salicyl­idene)benzyl­amine

The title complex, [μ-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.
