Özet

Recently, hydrothermal synthesis and characterization of organic-inorganic hybrid materials has attracted great attention.A novel organic-inorganic hybrid material, [Cu(en)MoO4], was hydrothermally synthesized as blue crystals. A mixture of Na2MoO4 CuCl2 NaCl, ethylenediamine and water was loaded into a 23 mL autoclave and heated at 170°C for 72 h. The compound crystallizes in the space group P2(1)/c of the monoclinic system with four formula units in a cell of dimensions a . 7.6743(15) b . 9.4364(19)c . 9.9538(2) . 72.266(3) V . 686.6(2) The structure is composed of {MoO4}tetrahedra and {CuN2O4} octahedra. Each pair of copper octahedra forms a binuclear edge-sharing unit through a {Cu2O2} interaction. The binuclear octahedral units are interconnected through the bridging {MoO4} yielding a layer structure.Purple crystals of a known hybrid material, [Cu(en)2]2[Mo8O26], was hydrothermally obtained under different reaction conditions. A mixture of Na2MoO4 ethylenediamine and water was loaded into the autoclave and heated at 170°C for 72 crystallizes in the space group Pbca of the orthorhombic system with eight formula units in a cell of dimensions a . 13.516 b . 15.548(3) c . 16.725(3) V . 3514.7(12) The structure consists of linked through groups. Each unit forms covalent interactions with two units.Green and black crystals were obtained from the reaction of with different ratios. Via the reaction of NaCl, ethylenediamine and yellow crystals were obtained.
