Novel three-dimensional host structure revealed in the crystal structure of N-methyl-1,3-diaminopropanecadmium(II) tetracyanonickelate(II)-cyclohexane(2/1)

The cavity accommodating the guest cyclohexane molecule in the title clathrate compound is topped and bottomed by the two-dimensionally extended catena-[cadmium(II) tetra-μ-cyanonickelate(II)] networks and walled by the chelate ring of the N-methyl-1,3-diaminopropane coordinate to the Cd atom and by another tetracyanonickelate (II) linkage involving the Cd atom.
