The metal complexes [Hg 2 (tbim) 2 Br 4 ]·2DMF ( 1 ) and [Hg 2 (tbim)I 4 ]·1.5DMF ( 2 ) were prepared by reactions of 1,3,5‐tris(benzimidazol‐1‐ylmethyl)‐2,4,6‐trimethylbenzene (tbim) with HgBr 2 , HgI 2 , respectively, and [Hg 2 (tbim)I 4 ]·0.5(FeCp 2 )·H 2 O ( 3 ) was obtained by the same method with addition of ferrocene (FeCp 2 ) as additive. Their structures were determined by X‐ray crystallographic analyses. Complex 1 has a macrocyclic binuclear structure with one benzimidazole arm of the ligand free of coordination and the binuclear units are further connected by C‐H···N hydrogen bonds to give an infinite zigzag chain. Complexes 2 and 3 have a 2D network structure in which tbim serves as a tridentate ligand. The results showed that the halides of bromide and iodide have remarkable impact on the structure of the complexes. The FeCp 2 molecules are trapped in the voids of framework 3 .
