Abstract

Through exploitation of hydrothermal synthesis, two new one-dimensional copper(II) molybdate chains containing a bidentate chelating and space filling ligand have been prepared. [Cu(bpy)Mo4O13] (bpy = 2,2′-bipyridine) (1), and [Cu(pyrpyrz)Mo2O7] (pyrpyrz = 2,3-bis(2-pyridyl)pyrazine) (2). The structure of 1 exhibits a one-dimensional chain of edge-and-corner-sharing {MoO6} octahedra, decorated with {Cu(2,2′-bpy)}2+ groups attached through bridging oxo-groups. The structure of 2 consists of an infinite {Mo2O7}n2n- ribbon of edge sharing molybdenum square pyramids and octahedra. The octahedral molybdenum centers are edge sharing to the copper octahedra which in turn corner share to the square pyramidal molybdenum centers. The nitrogen donors of the ligand occupy one axial and one equatorial site of the copper centers.
