La La Hf Ti
(La)2HfTi crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two lanthanum molecules and two HfTi clusters. In each HfTi cluster, Hf(1) is bonded in a 1-coordinate geometry to one Ti(1) atom. The Hf(1)-Ti(1) bond length is 2.13 Å. Ti(1) is bonded in a 1-coordinate geometry to one Hf(1) atom.
