The structure of [M(H 2 O) 6 ][LiFe (ox) 3 ] (M=Mn , Fe ) – A heterobimetallic 2-D tris(oxalato) framework compound.

[MnIIxFeII1−x(H2O)6][LiFeIII(ox)3] (with 0 ≤ x ≤ 1) crystallizes in the space groupP31cwitha = 9.341(3) Å,c = 10.226(3) Å,c/a = 1.0947, andV = 772.8(5) Å3forZ = 2. The compound has a layered structure with two enantiomeric layers per unit cell. The layers are built up by an iron and lithium oxalate framework with intercalated M(II)-water octahedra of the formula [MnIIxFeII1−x(H2O)6][MIMIII(ox)3]. The value ofxcannot be specified at present. The structure displays intermolecular hydrogen bonding between the layers. [ABSTRACT FROM AUTHOR]
