Potassium Heptachlorodioxodimolybdate(V), KMo 2 O 2 Cl 7 KMo 2 O 2 Cl 7 was obtained at 400 °C from the reaction of SCl 2 with molybdenum which contained traces of potassium. Its crystal structure is monoclinic, space group C 2/ c , a = 1094.1, b = 1139.1, c = 1018.0 pm, β = 110.16°, Z = 4. In the Mo 2 O 2 Cl 7 – ion two coordination octahedra share a common face with three chlorine atoms. The crystal structure can be derived from the CsNiCl 3 type by vacating one third of the Ni and two thirds of the Cs positions. The crystallographic group‐subgroup relationship is given.
