A new layered zirconium phosphate 
Co(dien)2[Zr4H8P5O26]·3H2O (denoted ZrPO-CJ37) has been synthesizedhydrothermally by using a racemic mixture of a chiral cobaltammine complex Co(dien)2Cl3 as the template. Itsstructure is determined by single-crystal X-ray diffraction analysis and further characterized by X-ray powder diffraction,inductively coupled plasma, thermogravimetric, UV-vis, and photoluminescence analyses. The inorganic layer ofZrPO-CJ37 is built up from the linkage of Zr-centered octahedra and P-centered tetrahedra via vertex oxygenatoms forming a 4.6-net sheet. Its structure features the edge-sharing chains of Zr(OM)6 (M = P, H) octahedra.The cobaltammine complex cations are located in the interlayer region and interact with the host network throughH bonds. ZrPO-CJ37 exhibits interesting photoluminescence in the UV-vis spectral region. The edge-sharing chainsof Zr(OM)6 octahedra in the inorganic layer might be responsible for this unusual photoluminescence.
