A new selenite-sulfate compound Co3(SeO3)(SO4)(OH)2 was prepared using a typical hydrothermal reaction. This compound is found to crystallize in an orthorhombic space group of Pnma, featuring a 2D distorted kagomé structure composed of linear and zigzag Co-chains, in which the magnetic ions construct different isosceles-triangles. Our results of magnetic and specific heat measurements confirm a canted antiferromagnetic order at TN ∼ 29 K. Further, the successive field-induced metamagnetic transitions can be observed at Hc1 ∼ 1 T, Hc2 ∼ 23 T, and Hc3 ∼ 27 T, respectively. A clear magnetic hysteresis loop with a coercive field (Hc) of ∼1.4 T is also observed.
