Dm. Proserpio et al., POSSIBLE HARD MATERIALS BASED ON INTERPENETRATING DIAMOND-LIKE NETWORKS, Journal of the American Chemical Society, 116(21), 1994, pp. 9634-9637
Interpenetrating diamondoid nets, where one diamond-type framework is
formed by BeF2 and the other by SiO2 or GeO2, are constructed, and the
ir electronic structure has been studied. It is suggested that these w
ill be very hard materials.
