ABSTRACT: The high quality single crystals of Yb5Co4Ge10 have been grown by the indium metal flux method and characterized by means of
single crystal X-ray diffraction data. Yb5Co4Ge10 crystallizes in the Sc5Co4Si10 structure type,
tetragonal space group P4/mbm and lattice constants are a = b = 12.6369(18) ? and c = 4.1378(8) ?. Crystal
structure of Yb5Co4Ge10 composed of
three-dimensional [Co4Ge12] network having five, six and
eight membered rings. The three non-equivalent Yb atoms are sandwiched in three
different channels created by the [Co4Ge12] network.
Based on the bond length analysis from the crystallographic information, we
confirmed that Yb1 and Yb2 atoms are in the trivalent magnetic state and Yb3 is
in the divalent non-magnetic state.
