Etude structurale de Li2MnO3

Li2MnO3; Mr = 116.82 g.mol−1; cell parameters: a = 4.921(6)Å, b = 8.526(3)Å, c = 9.606(5)Å, β = 99.47(5)°, V = 397.5(8)Å3; Dc = 3.90g.cm−3; monoclinic, space group: C2c; R = 0.041 and Rw = 0.050 for 394 reflections. The crystal structure was reinvestigated from a single crystal on an automatic diffractometer. All the atoms belonging to this structure are octahedrally surrounded and the structure of this compound is deriving from the NaCl type structure. The crystal structure study shows a partial substitution disorder involving a part of lithium and manganese atoms.
