Na As As P
NaAs2P crystallizes in the triclinic P1 space group. Na(1) is bonded in a distorted water-like geometry to four equivalent As(2) and two equivalent P(1) atoms. There are a spread of Na(1)-As(2) bond distances ranging from 2.56-3.17 Å. There is one shorter (1.57 Å) and one longer (1.90 Å) Na(1)-P(1) bond length. There are two inequivalent As sites. In the first As site, As(1) is bonded in a 5-coordinate geometry to two equivalent As(1), two equivalent As(2), and one P(1) atom. Both As(1)-As(1) bond lengths are 2.86 Å. There is one shorter (2.71 Å) and one longer (2.95 Å) As(1)-As(2) bond length. The As(1)-P(1) bond length is 2.59 Å. In the second As site, As(2) is bonded in a 9-coordinate geometry to four equivalent Na(1), two equivalent As(1), two equivalent As(2), and one P(1) atom. Both As(2)-As(2) bond lengths are 2.86 Å. The As(2)-P(1) bond length is 2.59 Å. P(1) is bonded in a water-like geometry to two equivalent Na(1), one As(1), and one As(2) atom.
