Alkali metal - Wikipedia

While most metals form arsenides, only the alkali and alkaline earth metals form mostly ionic arsenides. The structure of Na 3 As is complex with unusually short Na–Na distances of 328–330 pm which are shorter than in sodium metal, and this indies that even with these electropositive metals the bonding cannot be straightforwardly ionic.
