A novel copper(II) chromate complex of the formula [Cu(bpy) 3 ][CrO 4 ]·7.5H 2 O (1) (bpy=2,2′-bipyridine) was prepared in the crystalline form and characterized by X-ray diffraction and spectroscopic methods (EPR, FIR-IR, NIR–Vis–UV). Two non-equivalent [Cu(bpy) 3 ] 2+ groups in the form of tetragonally elongated octahedron are built into the hydrogen-bonded...
Two novel complexes of Zn(II) chromate with 2,2'-bipyridine have been synthesised: [Zn(bpy) 3 ]CrO 4 .7.5H 2 O (1) and catena-(μ-CrO 4 -O,O')[Zn(bpy)(H 2 O) 2 ].2H 2 O (2). Complex 1 has been characterised by a structural method. The [Zn(bpy) 3 ]CrO 4 .7.5H 2 O crystals have a monoclinic symmetry with space group C2/c...
