Synthesis, crystal structure and luminescent property of heterometallic d10–d8 porous complex.

One new heterometallic complex [Cd 2 Cu(BTC) 2 (H 2 O) 2 ]⋅2H 2 O ( 1 ) (BTC = benzene-1,3,5-tricarboxylate), has been synthesized and characterized by elemental analysis and single-crystal X-ray diffraction techniques. The structure indicates that the complex 1 crystallizes in triclinic, space group P ī, in which, the carboxylate groups of BTC ligand adopt μ 2 –η 1 :η 1 , and μ 2 –η 2 :η 1 coordination modes, bridging Cd(II) and Cu(II) atoms to generate 2D Cd-BTC bilayer then to a (4,6)-connected open 3D framework with 1D channels occupied by guest water molecules. In addition, thermal gravimetric analysis (TGA) and luminescent property of 1 were investigated. [ABSTRACT FROM AUTHOR]
