disorder in main residue; R factor = 0.046; wR factor = 0.109; data-to-parameter ratio = 12.9. Boron carbide phases exist over a widely varying compos-itional range B12+xC3-x (0.06 < x < 1.7). One idealized structure corresponds to the B13C2 composition (space group R3m) and contains one icosahedral B12 unit and one linear C—B—C chain. The B12 units are composed of crystallographically distinct B atoms BP (polar, B1) and BEq (equatorial, B2). Boron icosahedra are interconnected by C atoms via their BEq atoms, forming layers parallel to (001), while the B12 units of the adjacent layers are linked through intericosahedral BP— BP bonds. The unique B atom (BC) connects the two C atoms of adjacent layers, forming a C—B—C chain along [001]....
