Interpretation of the IR Spectrum of Manganese Cyclotetraphosphate Mn₂P₄O₁₂ and Vibrational Analysis of the Cycle P₄O₁₂⁴-
Pages: 10-17

Abstract

The X-ray diffraction structural study showed that the cyclotetraphosphate of manganese, Mn2P4O12 crystallizes in the monoclinic system, Z = 4, with space group C2/c (C62h), with the following lattice parameters: a = 11.883 (1) Å - b = 8.588 (2) Åc = 10.137 (1) Å, β = 119.21 (2) °. The crystal lattice contains 4 cycles P4O124- with symmetry Ci. All the atoms occupy the sites " 8f " of symmetry C1 except manganese Mn atoms, which are non equivalent, half occupy the 4 sites "e" of  symmetry Ci and the other half occupy the 4 sites "d" of symmetry C2.
