Crystal Structures of Two Metal-Organic Frameworks Based on Zn(II) and 2,5-Diiodoterephthalate
Three-dimensional coordination polymers Cat 2 [{Zn 4 O} 2 (H 2 O) 2 (2,5-I-bdc) 7 ] ( 1 ) (2,5-I-bdc = 2,5-diiodoterephthalate, Cat is dimethylammonium) and [Zn 2 (2,5-I-bdc) 2 dabco] ( 2 ) (dabco is 1,4-diazobicyclo [2.2.2]octane) are prepared. The structures of 1 and 2 are determined by single cry...

has a halogen bond between guest DMF molecules and the MOF iodine atom. The I⋯O distances are 2.93-3.03 Å. |
