Y Hf Hf Mn
YHf2Mn is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two YHf2Mn clusters. Y(1) is bonded in a 3-coordinate geometry to two equivalent Hf(1) and one Mn(1) atom. Both Y(1)-Hf(1) bond lengths are 1.11 Å. The Y(1)-Mn(1) bond length is 1.11 Å. Hf(1) is bonded in a 3-coordinate geometry to one Y(1), one Hf(1), and one Mn(1) atom. The Hf(1)-Hf(1) bond length is 1.11 Å. The Hf(1)-Mn(1) bond length is 1.11 Å. Mn(1) is bonded in a 3-coordinate geometry to one Y(1) and two equivalent Hf(1) atoms.
