A series of 4f–5f heteronuclear metallic complexes were synthesized by a hydrothermal route from mixtures of uranyl acetate, lanthanide nitrate, and 1,2,4,5‐benzenetetracarboxylic acid (H 4 BTA) in an aqueous system. Single‐crystal X‐ray analysis revealed that the thirteen UO 2 ‐Ln‐BTA complexes ([(UO 2 ) 1.5 Ln(C 10 O 8 H 2 ) 1.5 (H 2 O) x ]⋅ y H 2 O; Ln=La ( 1 ), Ce ( 2 ), Pr ( 3 ), Nd ( 4 ), Sm ( 5 ), Eu ( 6 ), Gd ( 7 ), Tb ( 8 ), Dy ( 9 ), Ho ( 10 ), Er ( 11 ), Tm ( 12 ), Yb ( 13 ); x =6 for 1 – 4 , x =5 for 5 – 13 ; y =0 for 4 , y =1 for 3 , y =2 for 2 , y =3 for 5 , 9 , 10 , 12 , 13 , y =4 for 1 , 6 , 7 , 8 , 11 ) are isomorphous with three‐dimensional structures. For the purpose of developing potential applications of the UO 2 ‐Ln‐BTA complexes, we investigated their surface photovoltage and photocatalytic properties. In addition, the thermogravimetric analysis and photoluminescent properties of these complexes were also studied in detail.
