Abstract:A new compound, {Na2(H2O)4]2γ-Mo8O26(Gly-Gly)2]}·4H2O, was synthesized and characterized by elemental analyses, IRand single crystal X-ray diffraction. The compound crystallizes with triclinic symmetry in the space group P1 with a=0. 94166(9) nm, b=1. 13098(8) nm, c=1. 17804 (8) nm, α=63. 768(6)°,β=74. 231(5)°, γ=82. 402(6)°, V=1. 08294(15) nm3, Z=1, R1= 0. 0329, wR2= 0. 0925. The Gly-Gly ligands are coordinated via their carboxylate-oxyyen atoms at the vacant sites on the two five-coordinate molybdate for the centrosymmetric γ-Mo8O26]]4-anion. Because of weak interaction between the unit of γ-Mo8O26(Gly-Gly)2] and Na2(H2O)4] unit, one infinite 2D layer can be constructed.
Keywords:Organic-inorganic hybrid material  Polyoxometalate  Glycyclglycine  Crystal structure
