The material described by K2Zr(NH2)6 crystallizes in the trigonal R-3c space group. K(1) is bonded in a 6-coordinate geometry to three equivalent H(1) and three equivalent H(2) atoms. Zr(1) is bonded in an octahedral geometry to six equivalent N(1) atoms. N(1) is bonded in a distorted water-like geometry to one Zr(1), one H(1), and one H(2) atom. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one K(1) and one N(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one K(1) and one N(1) atom. is represented by the CIF file [CIF]
