Na2RhP crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Na2RhP cluster. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a single-bond geometry to one Na(2) atom. The Na(1)-Na(2) bond length is 0.97 Å. In the second Na site, Na(2) is bonded in a distorted single-bond geometry to one Na(1) and one Rh(1) atom. The Na(2)-Rh(1) bond length is 0.98 Å. Rh(1) is bonded in a bent 120 degrees geometry to one Na(2) and one P(1) atom. The Rh(1)-P(1) bond length is 0.23 Å. P(1) is bonded in a single-bond geometry to one Rh(1) atom.
