4,5-Diiodo-1-H-imidazole-derived linker ligand and Cu(I) and Co(II) coordination polymers based thereupon.

A new iodine-rich imidazole derivative 1,4-bis(4,5-diiodo-1H-imidazol-1-yl)butane (bimbI4, 1) features multiple I⋯I interactions in the solid state. Using 1 as a precursor, we prepared 1D and 2D coordination polymers of Co(II) and Cu(I) – {[Co(bimbI4)Cl2]·1.5DMF}n (2) and {[Cu2I2(bimbI4)]}n (3), respectively, also featuring extended systems of halogen bonds within their structures.
