The structure of the novel
ternary aluminide Ce3Pt4Al6 was refined from
X-ray single crystal data in the orthorhombic space group Pnma with a
= 13.6589(2), b = 4.3331(1), c = 17.4740(3) Å, Z = 4; R = 0.049. The structure can be
described as built up from platinum centered trigonal prisms formed by cerium
and aluminum atoms. These prisms form infinite columns in the [010] direction
by sharing triangular faces. The columns are condensed into groups by edge
sharing of the constituent trigonal prisms.
