The material structure described by K2Na(NH2)3 crystallizes in the tetragonal P4_2/m space group. There are three inequivalent K sites. In the first K site, K(1) is bonded in a distorted trigonal pyramidal geometry to four equivalent N(2) atoms. In the second K site, K(2) is bonded in a 4-coordinate geometry to four equivalent H(3) atoms. In the third K site, K(3) is bonded in a 10-coordinate geometry to two equivalent N(1), two equivalent N(2), two equivalent H(1), two equivalent H(2), and two equivalent H(3) atoms. Na(1) is bonded in a 3-coordinate geometry to one N(1) and two equivalent N(2) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a distorted water-like geometry to two equivalent K(3), one Na(1), and two equivalent H(3) atoms. In the second N site, N(2) is bonded in a distorted water-like geometry to one K(1), one K(3), one Na(1), one H(1), and one H(2) atom. There are three inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one K(3) and one N(2) atom. In the second H site, H(2) is bonded in a single-bond geometry to one K(3) and one N(2) atom. In the third H site, H(3) is bonded in a single-bond geometry to one K(2), one K(3), and one N(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
