“…Several phosphates in this system are crystallographically well characterized. AgV III P 2 O 7 and AgV III 2 (PO 4 )(P 2 O 7 ) are containing vanadium(III). Ag 2 (V IV O)(P 2 O 7 ) and Ag 2 (V V O 2 )(PO 4 ) with vanadium(IV) and vanadium(V) as well as mixed‐valent Ag(V IV O)(V V O)(PO 4 ) 2 have been tested as catalyst material for the selective oxidation of n ‐butane.…”

Ag 6 (V IV O) 2 (PO 4 ) 2 (P 2 O 7 ) was obtained by reaction of Ag 3 PO 4 and (VO) 2 P 2 O 7 (sealed ampoule, 550°C, 3 d). The crystal structure of the new mixed ortho-pyrophosphate was determined from X-ray single-crystal data [Pnma, Z = 4, a = 12.759(3) Å, b = 17.340(4) Å, c = 6.418(1) Å, R 1 = 0.071, wR 2 = 0.184 for 3174 unique reflections with F o Ͼ 4σ(F o ), 141 variables]. Ag + ions are located in between layers [(V IV O) 2 (PO 4 ) 2 (P 2 O 7 )] 6-. Equilibrium relations of the * Prof. Dr. R. Glaum E-Mail: rglaum@uni-bonn.de [a]424 new phosphate to neighboring phases were determined. The electronic structure of the (V IV ϵO) 2+ group was investigated by polarized electronic absorption spectroscopy (ν 1a = 9450 cm -1 , ν 1b = 9950 cm -1 , ν 2 = 14750 cm -1 ), EPR spectroscopy [X-and Q-band, powder and single crystal, orthorhombic crystal g-tensor with g 1 = 1.9445(3), g 2 = 1.9521(3), g 3 = 1.9695(3)], and magnetic measurements (powder, μ exp /μ B = 1.71, Θ p = -1.7 K).

Crystal Structure and Orbital-Singlet State of Ag xVP2O7. -Polycrystalline samples of Ag xVP2O7 (0.7  x  0.9) are prepared by solid state reaction of mixtures of composition 2xAg 3PO4, 4xVPO4, 3(1-x)VPO5, and (3-x)V(PO3)3 (sealed quartz tubes, 1073 K, 12 h). Single crystals of AgVP2O7 (x = 1) are prepared at 1323 K for 72 h. AgVP 2O7 crystallizes in the monoclinic space group P21/c with Z = 4 (single crystal XRD). The structure contains VO 6 octahedra which are bridged by P2O7 groups to form a three-dimensional network with hexagonal tunnels in which a pair of Ag ions is located. The samples are further characterized by measurements of the electrical resistivities and magnetic susceptibilities. The materials exhibit a singlet ground state electron configuration with a gap in the order of 10 K to the doublet state. The title system is expected to show a high voltage when applied as a positive electrode for lithium ion batteries. -(ONODA*, M.; SAKAMOTO, T.; J. Solid State Chem. 220 (2014) 132-136, http://dx.
