Abstract

Three-dimensional coordination polymers Cat₂[{Zn₄O}₂(H₂O)₂(2,5-I-bdc)₇] (1) (2,5-I-bdc = 2,5-diiodoterephthalate, Cat is dimethylammonium) and [Zn₂(2,5-I-bdc)₂dabco] (2) (dabco is 1,4-diazobicyclo [2.2.2]octane) are prepared. The structures of 1 and 2 are determined by single crystal X-ray diffraction. It is shown that the structure of 2 has a halogen bond between guest DMF molecules and the MOF iodine atom. The I⋯O distances are 2.93-3.03 Å.
