Temperature dependence of electrical resistivity for the BaTh2Fe4As4(N0.7O0.3)2 sample, indicating a superconducting transition at 30 K. The zero-resistance temperature is 22 K. The inset shows the crystal structure projected on the ac plane. The two constituent structural blocks, named "1111" and "122" respectively, are marked, and the inter-block charge transfer is shown by the arrow.
