%X The crystal structure of a mineral with the stoichiometry (K0.58Ba0.36)2(Ti0.93FeIII0.06)6O13 has been determined by X-ray diffraction and refined by full-matrix least squares to a residual of 0.076 for 1688 ?observed? reflections. Crystals are monoclinic, C2/m, a = 15.453(2), b = 3.8368(7), c = 9.123(2) &#506;,&#946; = 99.25(1)°, Z = 2, and are isostructural with the (Na,K,Rb)2Ti6O13 family. High-resolution electron microscopy has confirmed that the Ba and FeIII species (the latter in a high-spin state) are randomly substituted for K and Ti respectively.
