A New Heterometallic Pb(II)–Ca(II) Coordination Polymer with 2D Pb–O–Ca Inorganic Connectivity

Resumo

A new heterometallic-organic framework, namely [PbCa(Mbdc)₂(DMF)]_n (I) (H₂Mbdc = isophthalic acid, DMF = N,N'-dimethylformamide), was synthesized by the solvothermal reactions of Pb(NO₃)₂, Ca(NO₃)₂ · 4H₂O and H₂Mbdc. Single crystal X-ray diffraction analysis (CIF file CCDC no. 1567197) revealed that compound I features a 3D pillar-layered framework with 2D inorganic Pb–O–Ca connectivity. Thermal analysis indicated that the framework of compound I can be stable up to 320°C, and luminescent property investigation indicated that compound I exhibits intense luminescence at room temperature.
