Fe3B7O13Cl is rhombohedral, space group R3c, with ahex 8.6231(5), and chex 21.0503(5) Å, Z = 6; and arh 8.6035(7) Å, αrh 60.15(1)°; dc = 3.576. The final R = 0.038 (Rw = 0.054) for 1544 reflections. Bond lengths and bond angles do not differ significantly from, but are more accurate than, those reported for isostructural Fe2.4Mg0.6B7O13Cl (Dowty and Clark (1973). At. coordinates are given
