Abstract

A new dicobalt pyrophosphate, Co₂P₂O₇.6 H₂O, has been synthesized and characterized by single crystal X-ray diffraction. The compound belongs to the monoclinic space group P2₁/n, and its unit cell dimensions are: a = 7.2077(2), b = 18.3373(5), c = 7.6762(2) Å, β = 92.4356(15)°, V = 1013.64(5) Å³, Z = 4. The structural parameters were refined to an R index of 0.0570 for 1937 reflections with I > 2σ(I_o). The framework of this pyrophosphate is made by the packing of layers of discrete CoO₆ octahedra connected by double tetrahedra P₂O₇ groups. The (P₂O₇)^4- anion group shows bent eclipsed conformation. A comparative study among anhydrous (α-, β- and γ-Co₂P₂O₇) and hydrated forms (Co₂P₂O₇ . 2 H₂O) of dicobalt pyrophosphates known in literature is presented.
