Li(NH3)4C2H is Silicon tetrafluoride-derived structured and crystallizes in the tetragonal P4/n space group. The structure is zero-dimensional and consists of two acetylene molecules and two Li(NH3)4 clusters. In each Li(NH3)4 cluster, Li(1) is bonded in a tetrahedral geometry to four equivalent N(1) atoms. N(1) is bonded to one Li(1), one H(2), one H(3), and one H(4) atom to form distorted corner-sharing NLiH3 tetrahedra. There are three inequivalent H sites. In the first H site, H(2) is bonded in a single-bond geometry to one N(1) atom. In the second H site, H(3) is bonded in a single-bond geometry to one N(1) atom. In the third H site, H(4) is bonded in a single-bond geometry to one N(1) atom.

The structure is zero-dimensional and consists of two acetylene molecules and two Li(NH3)4 clusters. In each Li(NH3)4 cluster, Li(1) is bonded in a tetrahedral geometry to four equivalent N(1) atoms. All Li(1)-N(1) bond lengths are 2.07 Å. N(1) is bonded to one Li(1), one H(2), one H(3), and one H(4) atom to form distorted corner-sharing NLiH3 tetrahedra. The N(1)-H(2) bond length is 1.03 Å. The N(1)-H(3) bond length is 1.03 Å. The N(1)-H(4) bond length is 1.02 Å. There are three inequivalent H sites. In the first H site, H(2) is bonded in a single-bond geometry to one N(1) atom. In the second H site, H(3) is bonded in a single-bond geometry to one N(1) atom. In the third H site, H(4) is bonded in a single-bond geometry to one N(1) atom.
