Structure type , Z = 8 – s/c.c.p. Thin black lines: edges of two unit cells of the TMS structure; yellow balls and light-grey rods: the partial structure of the Si atoms, like the S22- dumbbells in the FeS2 pyrite structure (s); grey balls and grey rods: the partial structure of the C atoms, a distorted c.c.p. |
