LaTaZn is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two LaTaZn clusters. La(1) is bonded in a single-bond geometry to one Ta(1) atom. The La(1)-Ta(1) bond length is 1.64 Å. Ta(1) is bonded in a linear geometry to one La(1) and one Zn(1) atom. The Ta(1)-Zn(1) bond length is 0.58 Å. Zn(1) is bonded in a single-bond geometry to one Ta(1) atom.
