YTaP1Y crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two yttrium phosphide molecules and two YTa clusters. In each YTa cluster, Y(2) is bonded in a single-bond geometry to one Ta(1) atom. The Y(2)-Ta(1) bond length is 0.29 Å. Ta(1) is bonded in a single-bond geometry to one Y(2) atom.
