The crystal structure of the new compound Co 5 Te 4 O 11 Cl 4 is described. It crystallizes in the triclinic system, space group P‐1 with the unit cell parameters a = 822.26(8) pm, b = 1029.7(1) pm, c = 1031.1(1) pm, α = 110.80(1)°, β = 97.950(9)°, γ = 98.260(9)° and Z = 2. The structure is layered along the bc–plane and built by [CoO 5 Cl], [CoO 4 Cl 2 ] and [CoO 4 Cl] polyhedra sandwiched by [TeO 3 E ] and [TeO 4 E ] polyhedra. The layers can be regarded as infinite molecules without any net charge and only weak van der Waals forces connect them to each other. The halides and the lone‐pair, E , of Te IV protrude from the layers.
