NaBP2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two NaBP2 clusters. Na(1) is bonded in a water-like geometry to one B(1) and two equivalent P(1) atoms. The Na(1)-B(1) bond length is 1.21 Å. Both Na(1)-P(1) bond lengths are 0.52 Å. B(1) is bonded in a 3-coordinate geometry to one Na(1) and two equivalent P(1) atoms. Both B(1)-P(1) bond lengths are 1.25 Å. P(1) is bonded in a single-bond geometry to one Na(1) and one B(1) atom.
