Abstract	The crystal structure of (C12H24O6· K)2K[Co(OH)6Mo6O18]·12H2O has been determined by X-ray diffraction. Crystal data as follows ; monoclinic, space group C2/m, a = 22.512(4) Å, b = 18.304(4) Å, c = 7.641(1) Å, β = 90.52(2) Å, and Z = 2. A final conventional R value of 0.044 was obtained by least-squares refinement of 4173 independent observed [│Fo│≥ 3σ(│Fo│)] reflections. The [Co(OH)6Mo6O18]-3 polyanion shows the well-known Anderson-structure and has approximate 3m symmetry. A [Co(OH)6Mo6O18]-3 polyanion is located between two crown ether complexed cations forming a sandwich structure. One potassium ion interacts with the crown ether via electrostatic interactions. The other potassium ion only interacts with the water molecules and terminal oxygen atoms of the polyanion.
