The compound described by RbLi(NH2)2 crystallizes in the orthorhombic Pnma space group. Rb(1) is bonded in a 8-coordinate geometry to two equivalent N(2), two equivalent H(3), and four equivalent H(1) atoms. Li(1) is bonded to one N(2) and three equivalent N(1) atoms to form a mixture of distorted edge and corner-sharing LiN4 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 2-coordinate geometry to three equivalent Li(1), one H(1), and one H(2) atom. In the second N site, N(2) is bonded in a distorted water-like geometry to two equivalent Rb(1), one Li(1), and two equivalent H(3) atoms. There are three inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to four equivalent Rb(1) and one N(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one N(1) atom. In the third H site, H(3) is bonded in a single-bond geometry to one Rb(1) and one N(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
