Abstract: By reaction of zinc chloride and zinc bromide with hexamethylenetetramine in water/methanol crystals of the adducts ZnCl2 • C6H12N4 and ZnBr2 • C6H12N4, resp. were obtained. The compounds are isotypic, they crystallize in the orthorhombic space group P21am (non-standard setting of space group Pmc21, No. 26), Z = 2. The lattice parameters of the zinc chloride adduct are a = 1168.0(4), b = 685.7(4), and c = 601.1(4) pm, of the zinc bromide adduct a - 1188.9(6), b = 721.5(5), and c = 602.3(4) pm. The adducts are polymeric, they form parallel chains in the crystal. The zinc atoms are bonded to two halogen atoms and, via nitrogen atoms, to two hexamethylenetetramine molecules, which act as bidentate ligands. The coordination of the zinc atoms is approximately tetrahedral.
