The Figure shows the DC unit cell. If you first ignore the nuered atoms, the remainder form an FCC lattice; the atoms nuered 1-4 are then additional atoms loed in half of the tetrahedral interstitial spaces. As the tetrahedral hole is far too small to accommodate a full-sized atom, the others are pushed further apart, lowering the density.
