La La Co Co
LaCo1 is gamma CuTi structured and crystallizes in the monoclinic C2/m space group. The structure is zero-dimensional and consists of two LaCo1 clusters. La(1) is bonded in a water-like geometry to one La(1) and one Co(1) atom. The La(1)-La(1) bond length is 1.60 Å. The La(1)-Co(1) bond length is 2.54 Å. Co(1) is bonded in a distorted single-bond geometry to one La(1) atom.
