We report the successful synthesis and magnetic characterization of Cu3(OH)4SO4 which contains Cu triple chains of two non-equivalent Cu2+ ions, Cu1 and Cu2[1]. Antlerite, Cu3(OH)4SO4, was proposed to be a candidate of an idle-spin magnetic system, with long-range ferromagnetic ordering in the Cu2 central chains and AFM ordering between Cu2-Cu1-Cu2 chains[2]. Recently, it was proposed that the central chains of Cu1 also contribute to field-induced phases. Then it is questioning the proposed picture of Antlerite being an idle spin system[3]. We employed hydrothermal synthesis methods to prepare a phase pure microcrystalline Antlerite polycrystalline sample which we characterized by X-ray diffraction, magnetic susceptibility, heat capacity and high field magnetization measurements.
