KCa(NH2)3 crystallizes in the monoclinic P2_1/c space group. K(1) is bonded in a 13-coordinate geometry to one N(3), two equivalent N(1), two equivalent N(2), one H(3), one H(4), two equivalent H(1), two equivalent H(2), and two equivalent H(5) atoms. Ca(1) is bonded to two equivalent N(1), two equivalent N(2), and two equivalent N(3) atoms to form distorted face-sharing CaN6 octahedra. There are three inequivalent N sites. In the first N site, N(1) is bonded in a distorted water-like geometry to two equivalent K(1), two equivalent Ca(1), one H(1), and one H(3) atom. In the second N site, N(2) is bonded in a distorted water-like geometry to two equivalent K(1), two equivalent Ca(1), one H(2), and one H(4) atom.

In the first H site, H(1) is bonded in a single-bond geometry to two equivalent K(1) and one N(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to two equivalent K(1) and one N(2) atom. In the third H site, H(3) is bonded in a single-bond geometry to one K(1) and one N(1) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one K(1) and one N(2) atom. In the fifth H site, H(5) is bonded in a single-bond geometry to two equivalent K(1) and one N(3) atom. In the sixth H site, H(6) is bonded in a single-bond geometry to one N(3) atom.
