Atmospheric Carbon Dioxide Capture as Carbonate into a Luminescent Trinuclear Cd(II) Complex with Tris(2-aminoethyl)amine Tripodal Ligand

Spontaneous atmospheric CO2 capture as carbonate anion occurred in the synthesis of a trinuclear Cd(II) complex with tris(2-aminoethyl)amine ligand. In reaction two types of compounds were obtained and structurally characterized by X-ray diffraction on a single crystal: initially [{Cd(tren)}(3)(tren)](ClO4)(6)center dot 2H(2)O (1) and subsequently [{Cd(tren)}(3)(tren)][{Cd(tren)}(3)(mu(3)-eta CO3)](ClO4)(10) (2). The carbonate anion replaces partially the bridging tren molecule and coordinates in a mu(3) fashion. The luminescent properties of the compounds were investigated.
