The crystal structure of boron-doped superconducting Mg C1-x Bx11 Ni3, studied by powder neutron diffraction, is reported. The solubility limit of boron is determined to be approximately x=0.16. The unit cell expands from a=3.810 89 (2) Å to 3.819 66 (2) Å as x increases from x=0 to x=0.155. Boron (B11) doping decreases Tc with increasing x: from 7.09 K (x=0) to 6.44 K (x=0.155).
