Materials Data on KZnN by Materials Project
KZnN crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. K1+ is bonded in a 4-coordinate geometry to four equivalent N3- atoms. There are two shorter (2.95 Å) and two longer (3.00 Å) K–N bond lengths. Zn2+ is bonded in a 2-coordinate geometry to three equivalent N3- atoms. There are two shorter (1.90 Å) and one longer (2.56 Å) Zn–N bond lengths. N3- is bonded to four equivalent K1+ and three equivalent Zn2+ atoms to form a mixture of distorted corner and edge-sharing NK4Zn3 pentagonal bipyramids.
