Ivashkevich, Alexander S. Lyakhov, Anatoly F. Selevich, Anatoly I. Lesnikovich] The crystal structure of indium hydrogen phosphate hydrate, In3(H3O)(H2PO4)6(HPO4)2 · 4H2O, has been determined from X-ray powder diffraction data by using direct methods (EXPO program), and refined by FULLPROF package to RBragg value of 5.6%. The structure is monoclinic, space group C2/c (No. 15), unit cell dimensions a = 17.0835(5), b = 9.6795(3), c = 17.8776(4) Å, β = 90.301(2)°, V = 2956.2(1) Å3, Z = 4, Dx = 2.73 g/cm3. Hydrogen atoms were placed on calculated positions. There are two unique indium atoms in the crystal structure. InO6 octahedra are connected together via the corners of PO4 tetrahedra to form layers parallel to the xy plane. The layers are linked together by water molecules, located in the interlayer space, through their hydrogen bonds. Within the layers there are hollows occupied by oxonium cations. The compound was found to be isostructural with salts of the composition M III3MI(H2PO4)6(HPO4)2 · 4H2O, where M III-trivalent metal, M I-monovalent metal, oxonium or ammonium. © 2004 Oldenbourg Wissenschaftsverlag GmbH Crystallography nationallicence Inorganic chemistry nationallicence Organic chemistry nationallicence Ivashkevich Ludmila S. aut Lyakhov Alexander S. aut Selevich Anatoly F. aut Lesnikovich Anatoly I. aut Zeitschrift für Kristallographie - Crystalline Materials De Gruyter Oldenbourg 219/9(2004-09-01), 543-547 2194-4946 219:9<543 2004 219 zkri https://doi.org/10.1524/zkri.219.9.543.44042 text/html Onlinezugriff via DOI 1 research article jats NATIONALLICENCE 856 40 https://doi.org/10.1524/zkri.219.9.543.44042 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Ivashkevich Ludmila S. aut NATIONALLICENCE 700 1- Lyakhov Alexander S. aut NATIONALLICENCE 700 1- Selevich Anatoly F. aut NATIONALLICENCE 700 1- Lesnikovich Anatoly I. aut NATIONALLICENCE 773 0- Zeitschrift für Kristallographie - Crystalline Materials De Gruyter Oldenbourg 219/9(2004-09-01), 543-547 2194-4946 219:9<543 2004 219 zkri CC0 http://creativecommons.org/publicdomain/zero/1.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-gruyter
