KY(NH2)4 crystallizes in the monoclinic C2/c space group. K(1) is bonded in a 8-coordinate geometry to four equivalent N(1), two equivalent H(2), and two equivalent H(4) atoms. Y(1) is bonded to two equivalent N(1) and four equivalent N(2) atoms to form edge-sharing YN6 octahedra. 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(1), one Y(1), one H(2), and one H(4) atom. In the second N site, N(2) is bonded in a distorted water-like geometry to two equivalent Y(1), one H(1), and one H(3) atom. There are four inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one N(2) atom. In the second H site, H(2) is bonded in a single-bond geometry to one K(1) and one N(1) atom. In the third H site, H(3) is bonded in a single-bond geometry to one N(2) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one K(1) and one N(1) atom.
KY(NH2)4 crystallizes in the monoclinic C2/c space group. K(1) is bonded in a 8-coordinate geometry to four equivalent N(1), two equivalent H(2), and two equivalent H(4) atoms. There are two shorter (2.90 Å) and two longer (2.95 Å) K(1)-N(1) bond lengths. Both K(1)-H(2) bond lengths are 2.89 Å. Both K(1)-H(4) bond lengths are 2.74 Å.
