The discovery of high temperature superconductivity under high pressure in La₃Ni₂O₇ has led to predictions that the isostructural compound Sr₃Ni₂O₅Cl₂ could exhibit superconductivity at ambient pressure. We successfully synthesized Sr₃Ni₂O₅Cl₂ and conducted detailed physical property measurements. Temperature dependence of electrical resistance revealed a gradual increase in resistance at low temperatures, suggesting metallic nature. In the future, we will synthesize high purity bulk samples and perform magnetic susceptibility and specific heat measurements to further understand the material's properties and achieve superconductivity.
