According to the results of electron diffraction reported in the literature this carbon allotrope has a space group Fm \(\bar{3}\) m (group number 225) with a lattice parameter of about 3.54–3.57 Å. Nevertheless, because of the closeness of its lattice parameter to that of diamond...

The composition was determined as Hg[sub 2]Re[sub 0.5]Ba[sub 4]Ca[sub 1.5]O[sub 8.5] and an univocal interpretation was found in terms of the high-symmetry space group Fm3m(225), with Z=2, (=6.70 g/cm鲁; the reliability factor was 5.0%. This phase, Cu-free and not ...
