Y Fe Fe Pd
YFe2Pd is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two YFe2Pd clusters. Y(1) is bonded in a 3-coordinate geometry to two equivalent Fe(1) and one Pd(1) atom. Both Y(1)-Fe(1) bond lengths are 0.26 Å. The Y(1)-Pd(1) bond length is 0.27 Å. Fe(1) is bonded in a 2-coordinate geometry to one Y(1) and one Pd(1) atom. The Fe(1)-Pd(1) bond length is 0.26 Å. Pd(1) is bonded in a 3-coordinate geometry to one Y(1) and two equivalent Fe(1) atoms.
