description: LiZnSi3(C4N)4 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is one-dimensional and consists of two LiZnSi3(C4N)4 ribbons oriented in the (1, 0, 0) direction. Li1+ is bonded in a 6-coordinate geometry to three C+0.19- and three N3- atoms. There are a spread of Li–C bond distances ranging from 2.28–2.54 Å. There are a spread of Li–N bond distances ranging from 2.09–2.51 Å. Zn2+ is bonded in a distorted T-shaped geometry to one C+0.19- and two N3- atoms. The Zn–C bond length is 1.88 Å. There are one shorter (2.00 Å) and one longer (2.14 Å) Zn–N bond lengths. There are three inequivalent Si4+ sites. In the first Si4+ site, Si4+ is bonded in an L-shaped geometry to two C+0.19- atoms. There is one shorter (1.81 Å) and one longer (1.88 Å) Si–C bond length. In the second Si4+ site, Si4+ is bonded in a trigonal non-coplanar geometry to two C+0.19- and one N3- atom. There is one shorter (1.86 Å) and one longer (1.93 Å) Si–C bond length. The Si–N bond length is 1.73 Å.
