Syntheses, crystal structures and photochemistry of two new organic-inorganic hybrid compounds based on copper-glycin complexes and paradodecatungstates

Abstract: Two organic-inorganic hybrid materials built from copper-glycin complexes and paradodecatungstates, Na6[{Cu(gly)(H2O)}]2[{Cu(H2O)}(H2W12O42)] ⋅ 21H2O (1) and Na{Na(H2O)6}{Na(H2O)4}3[{Cu(gly)2}]2{H5(H2W12O42)} ⋅ 8.5H2O (gly = glycin) (2), have been synthesized in aqueous solution and characterized by IR, UV, TG, elemental analysis, electrochemistry, and single-crystal X-ray analyses. In 1, [H2W12O42]10- building block connects two neighboring clusters with [Cu(H2O)]2+ groups to produce an infinite 1-D chain; then these chains are linked through [Cu(gly)(H2O)]+ groups to form a 2-D layer structure, which is further joined by Na+ to form a 3-D network. In 2, [H2W12O42]10- decorated by two [Cu(gly)2] moieties connects four adjacent clusters with six Na+ into a 2-D layer. In addition, luminescence and photocatalysis properties of these compounds have been investigated.
