The low-density cubic form of silica (impure), melanophlogite, has a clathrate-type structure that incorporates organic molecules, including long straight-chain hydrocarbons. The structure is analogous to that of the clathrate crystalline hydrates of composition 6X·46H_2O or 8X·46H_2O. This is the first known example of a silicate framework structure with the pentagonal dodecahedron as a framework element.

The ideas in this paper were first presented at a meeting of the Mineralogical Society of Southern California, 14 October 1963, in Pasadena. The calculations for Table 4 were carried out on the IBM 7094 by means of the CRYRM system designed by R. E. Marsh and his collaborators, whose help I gratefully acknowledge.
