Solid state coordination chemistry of molybdenum oxides with 1,2,3-triazole (Htrz): The crystal structures of [Cu(I)Cu(II)2(trz)2Mo4O13(OH)], [MoO3(Htrz)0.5] and [Cu(I)trz]

Hydrothermal chemistry was used to prepare the bimetallic organic–inorganic hybrid oxide [Cu(I)Cu(II)2(trz)2Mo4O13(OH)] · 6H2O (1 · 6H2O). The structure consists of { HMo 4 O 14 } n 3 n - chains linked through { Cu 3 ( trz ) 2 } n 3 n + into a three-dimensional framework. The structures of the simple metal–triazole phases [MoO3(Htrz)0.5] (2) and [Cu(trz)] (3) are also reported. Compound 2 is two-dimensional, constructed from corner-sharing {MoO5N} octahedra. Compound 3 consists of {Cu(trz)}n chains linked through weak Cu⋯Cu contacts into a virtual layer.
