Magnetic and electronic nature have been investigated for the novel layered oxysulfide Sr2Cu2CoO2S2 (space group I/4mmm). Sr2Cu2CoO2S2 is the antiferromagnet with TN (= 200 K) determined by the measurements of neutron powder diffraction and magnetic susceptibility (χ). The χ shows a broad maximum indicative of two-dimensional antiferromagnetic nature, which is not originated from the (Cu+S)2 layers but the strongly correlated Co2+O2 square-planes revealed by the X-ray photoemission spectroscopy.
