Compounds containing bis‐chelate dianionic blocks {M(3d)(cbdc) 2 } 2– (M(3d)=V IV O, Cu II ) with cations VO 2+ and Cu 2+ chelated by two anions of dicarboxylic acid have been prepared as crystals when aqueous solutions of vanadyl sulfate VOSO 4 ⋅3H 2 O or copper sulfate CuSO 4 ⋅5H 2 O have been allowed to react with sulfates of d‐metals (Mn II , Co II , Ni II , Zn II , and Cd II ) and barium salt of cyclobutane‐1,1‐dicarboxylic acid (H 2 cbdc=C 4 H 6 (CO 2 H) 2 ) in the 1:1:2 ratio. The nature of the M(3d) metal center has been found to influence on the structure of the heterometallic compounds formed. 1D polymers [M(VO)(cbdc) 2 (EtOH) 2 (H 2 O) 3 ] n (M=Mn ( 1 ), Co ( 2 ), Ni ( 3 )), molecular dinuclear complex [Zn(VO)(cbdc) 2 (H 2 O) 5 ]⋅H 2 O ( 4 ), and 1D polymer {[Cd(VO)(cbdc) 2 (H 2 O) 5 ]⋅H 2 O} n ( 5 ) are formed when M(3d)=V IV O, whereas in the case of the bis‐chelate block with the Cu II atom, ionic compounds [M(H 2 O) 6 ][Cu(cbdc) 2 (H 2 O)] (M=Mn ( 6 ), Co ( 7 ), Ni ( 8 ), Zn ( 9 )) and 2D polymer {[CdCu(cbdc) 2 (H 2 O) 2 ]⋅2H 2 O} n have been synthesized. The isolation of paramagnetic centers in compounds 1–10 is confirmed by magnetic measurements and EPR spectroscopy.
