} was self-assembled with Cd
2+
at 100 ℃ using the solvothermal method. The structure and properties of this compound were characterized through single crystal X-ray diffraction, powder X-ray diffraction, thermogravimetry, SEM, EDS and solid-state fluorescence analysis. Results revealed that the complex constitutes a 1D ladder chain structure formed by the deprotonated oia
2-
and the N-containing ligand bpeh that are connected to the seven-coordinated Cd

centers. Furthermore, selective fluorescence experiments demonstrated that this coordination compound can simultaneously detect MnO
