N2 - © 2015, Springer-Verlag Berlin Heidelberg.Single crystals and powder samples of Co analogue of paganoite CoBiO(AsO4) have been obtained by high-temperature solid-state reactions. Crystal structure [triclinic, $$P\bar{ 1 }$$P1¯, a = 5.2380(3), b = 6.8286(4), c = 7.6150(4) Å, α = 111.631(2), β = 108.376(2), γ = 108.388(2)°, V = 209.55(2) Å3] has been refined to R1 = 0.018 on the basis of 1524 unique observed reflections. CoBiO(AsO4) is isotypic to paganoite, NiBiO(AsO4). The crystal structure can be described as based upon [OCoBi]3+ chains of edge-sharing (OBi2Co2) tetrahedra linked via (AsO4) groups. Differential thermal analysis reveals no phase decomposition till 850 °C, when the compound starts to melt. A small endothermic peak is observed near 330 °C. Thermal expansion has been studied by high-temperature powder X-ray diffraction. Thermal expansion coefficients (αa = 10.1 × 10−6, αb
