• Coordination polymer
• Flexible tri(imidazole) ligands
• Interpenetration
• Ferroelectric property

The hydrothermal reaction of CoCl2 center dot 6H(2)O, 4,4'-(ethene-1,2-diyl)dibenzoic acid (H2L) and 1,3,5-tris(imidazol-1-ylmethyl)-2,4,6-trimethylbenzene (titb) generates a new three-dimensional (3D) coordination polymer [Co(titb)(L)]center dot 3H(2)O (1). Compound 1 crystallizes in a noncentrosymmetric Cc space group and the topology analysis suggests it features a rare binodal (3,5)-connected (6(3))(6(9).8) hms net with 2-fold interpenetration, constructed by the 2D Co(titb)(2+) sheet pillared by L ligands via coordination to the Co atoms. Furthermore, the thermal and ferroelectric properties of 1 have also been studied.
