Single crystals of a novel distrontium cobalt diborate, Sr₂Co(BO₃)_2, were successfully obtained from the melt at 1200 °C of the polycrystalline material. The powder of Sr₂Co(BO₃)₂ compound was synthesized using standard solid state reaction at 850 °C. The refinement of the structure shows that Sr₂Co(BO₃)₂ crystallizes in the monoclinic cell with the space group C2/m. The crystal structure is built from [CoO₆] octahedra linked to [BO₃] triangles by the vertices and to the SrO₉ polyhedra by sharing two faces. The infrared analysis confirms the existence of BO₃ vibrations group's. The calculated gap energy is E_gap = 3.5eV for indirect gap model and E_gap = 3.75eV for direct gap one. The magnetic measurements show that antiferromagnetic interactions are predominant in the studied borate. The high temperature X-ray diffraction and the differential scanning calorimetry allow to observe two anomalies in the temperature range of 400–800 °C which correspond to the phase transitions of Sr₂Co(BO₃)₂.
