NaV2P crystallizes in the orthorhombic Amm2 space group. Na(1) is bonded to four equivalent Na(1), six equivalent V(1), and two equivalent P(1) atoms to form a mixture of distorted face, corner, and edge-sharing NaNa4V6P2 cuboctahedra. All Na(1)-Na(1) bond lengths are 3.18 Å. There are two shorter (3.61 Å) and four longer (3.84 Å) Na(1)-V(1) bond lengths. Both Na(1)-P(1) bond lengths are 3.50 Å. V(1) is bonded in a distorted single-bond geometry to three equivalent Na(1), one V(1), and four equivalent P(1) atoms. The V(1)-V(1) bond length is 0.81 Å. There are a spread of V(1)-P(1) bond distances ranging from 1.89-2.67 Å. P(1) is bonded in a 8-coordinate geometry to two equivalent Na(1) and eight equivalent V(1) atoms.
