Fig. 3: Coordination states of elements.

Element content of a Sr2TiO4-NF and b Sr2TiO4-N by ICP, ONH, and ion chromatograph analysis, deduced chemical formula are shown at the bottom (oxygen vacancies are represented by empty squares ‘□‘); c EPR spectra of Sr2TiO4-N and Sr2TiO4-NF measured at 100 K. d XAS spectra at Ti K-edges of Sr2TiO4-N and Sr2TiO4-NF, the shading areas correspond to the pre-edge and edge region; e XAS spectra at Ti L-edges of Sr2TiO4-N and Sr2TiO4-NF, L3 and L2 denote signals due to spin-orbit interactions whilst t2g and eg denote signals due to octahedral crystal field splitting; f XAS spectra at O K-edges of Sr2TiO4-N and Sr2TiO4-NF, O2p-t2g, O2p-eg, and O2p-Ti4sp denote the hybridized states between O 2p and Ti 3d and 4sp orbitals. Source data for element content, ESR spectra, and XAS spectra are provided as a Source Data file.
