Two coordination polymers, [M(Fpht)tib]·H2O (M = Cd 1, Co 2; H2Fpht = 3-fluorophthalic acid and tib = 1,3,5-tris(1-imidazolyl)benzene) have been synthesized and structurally characterized by single crystal X-ray diffraction. They possess unusual double layer structures constructed from M–Fpht helices and (3, 3) M–tib honeycom layers. The fluorescence of the complexes maybe arise from the intraligand π⁎–π transition.

► Unusual 2D double layer structure is constructed from Cd(II)/Co(II) ions with 3-fluorophthalic acid (H2Fpht) and 1,3,5-tris(1-imidazolyl)benzene) (tib).
► Each tib ligand connects three M(II) ions and each M(II) ion connects three tib ligands to generate an (3, 3) M–tib honeycom layer.
► M(II) ions are linked together by the Fpht ligands to form M–Fpht right- and left-handed helical chains.
► 3D supramolecular network is formed by C―H…π or π…π interaction.
