Na2SrP is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Na2SrP clusters. Na(1) is bonded in a 3-coordinate geometry to one Na(1), one Sr(1), and one P(1) atom. The Na(1)-Na(1) bond length is 1.51 Å. The Na(1)-Sr(1) bond length is 1.95 Å. The Na(1)-P(1) bond length is 1.95 Å. Sr(1) is bonded in a single-bond geometry to two equivalent Na(1) and one P(1) atom. The Sr(1)-P(1) bond length is 1.51 Å. P(1) is bonded in a 3-coordinate geometry to two equivalent Na(1) and one Sr(1) atom.
