Abstract
Single crystals of Co1.5Ti0.5(BO3)O (I) and Co1.5Zr0.5(BO3)O (II) were obtained by a B2O3 flux technique. Both compounds crystallize with or thorhombic symmetry, space group D-2h(16)-Pnma (Nr. 62), I a = 928.1; b = 311.1; c = 940.1 pm, Z = 4 and II a = 949.5: b = 323.42; c = 934.7 pm; Z = 4. The compounds are isotypic to the mineral warwickite. All metal ions are octahedrally coordinated by oxygen ions. The structure contains isolated. trigonal planar BO3 units and oxygen that is not co ordinated to boron.
