A novel coordination polymer {[Cd(BDAC)] 2 · H 2 O} n ( 1 ) [HBDAC = (1′H‐[2, 2′]biimidazoly‐1‐yl)‐acetic acid] was synthesized under hydrothermal conditions and characterized by elemental analysis and single‐crystal X‐ray diffraction. Complex 1 crystallizes in the acentric orthorhombic space group Ccc 2. The Cd1 atoms and BDAC 2– ligands construct [Cd1(BDAC)] rhomboid grid (4, 4)‐topology layer motifs, whereas the Cd2 atoms and BDAC 2– ligands form [Cd2(BDAC)] 1D coordination polymer ribbons. Furthermore, adjacent lay motifs are linked into 3D net structures by 1D coordination polymer ribbons with 4‐connected 3D trinodal {4 2 8 2 10 2 }{4 4 6 2 }{4 3 6 2 8} 2 topology. The measurement of electric hysteresis loops indicated that complex 1 displays a ferroelectric characteristic.
