摘要

A novel coordination polymer {[Cd(BDAC)] _2·H _2O} _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 Ccc2. 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 ~28 ~210 ~2}{4 ~46 ~2}{4 ~36 ~28} _2 topology. The measurement of electric hysteresis loops indicated that complex 1 displays a ferroelectric characteristic.
