K1.4P4W14O50: an odd-m member (m = 7) of the monophosphate tungsten bronze series KxP4O8(WO3)2m. Domenges, B.; Goreaud, M.In this study， 1314-35-8 and 18088-11-4 are also used.; Labbe, P.; Raveau, B. (Inst. Sci. Matiere Rayonnem., Univ. Caen, Caen 14032, Fr.). J. Solid State Chem., 50(2), 173-9 (English) 1983. CODEN: JSSCBI. ISSN: 0022-4596. DOCUMENT TYPE: Journal CA Section: 75 (Crystallography and Liquid Crystals) KxP4W14O50 (x = 1.4) is monoclinic, space group A2/m, with a 6.660(2), b 5.3483(3), c 27.06(5) ?, and b 97.20(2)°; Z = 1. The structure was refined to a final R = 0.036 and RW = 0.039 for 2436 reflections. This structure belongs to the structural family KxP4O8(WO3)2m, called monophosphate tungsten bronzes (MPTB), which is characterized by ReO3-type slabs of various widths connected through PO4 single tetrahedra. This bronze corresponds to the member m = 7 of the series and its framework is built up alternately of strands of 3 and 4 WO6 octahedra. The structural relation with the P4O8(WO3)2m series, called M'PTB, are described and the possibility of intergrowth between these 2 structures is discussed. .

Bronzes with a tunnel structure potassium monophosphate tungsten bronze (KxP4O8(WO3)2m): the tenth member of the series - KP8W40O136. Labbe, P.; Ouachee, D.; Goreaud, M.In this study， 1314-35-8 and 18088-11-4 are also used.; Raveau, B. (Lab. Cristallogr. Chim. Phys. Solide, Univ. Caen, Caen 14032, Fr.). J. Solid State Chem., 50(2), 163-72 (English) 1983. CODEN: JSSCBI. ISSN: 0022-4596. DOCUMENT TYPE: Journal CA Section: 75 (Crystallography and Liquid Crystals) KP8W40O136 is monoclinic, space group P21/c, with a 19.589(3) b 7.5362(4), c 16.970(3) ?, and b 91.864(14)°. The final R = 0.040 and Rw = 0.049 at. coordinate are given. The framework is built up from ReO3-type slabs connected through pyrophosphate groups. The structure is compared to those of the other members of the series: although the ReO3-type slabs show a different type of tilting of the WO6 octahedra, the dispersion of W-O distances is always higher for the octahedra linked to 1 or 2 P2O7 groups and decreases in proportion as W is farther from these groups. The perovskite cages of the slabs are described and compared to those encountered in the structures of WO3 and of the bronzes AxWO3. .
