A mix-charge cation solid-state borate oxide Co 3BO 5 has been synthesized and its structure has been determined by single-crystal X-ray methods. It crystallizes in the orthorhombic~ space group Pbam with cell parameters a=9.2963(2), b=11.948(2), c=2^9737(6) , V=330.30(12) 3, Z=4, M r=267.60, F(000)=504, μ=14.733, D calcd =5.381g/cm 3. The structure was determined from 853 unique reflections and refined to the final residuals R=0.0633 and wR=0.1457. It has two kinds of Co cations, Co 2+ and Co 3+ . It is composed of highly distorted [CoO 4] squares and triangular [BO 3] groups that are connected to form infinite two-dimensional layers.
