Abstract
The title compound, [Li(NH(3))(4)](+)[Li(NH(3))(3)S(3)](-), an ammo-niate of the previously unknown lithium tris-ulfide, was obtained from the reaction of lithium and sulfur in liquid ammonia. The asymmetric unit consists of two crystallographically independent formula units. The [Li(NH(3))(4)](+) cations are close to regular LiN(4) tetra-hedra. The anions contain LiSN(3) tetra-hedra; the S-S-S bond angles are 110.43 (5) and 109.53 (5)°. In the crystal, the components are linked by multiple N-H⋯S hydrogen bonds. A weak N-H⋯N hydrogen bond is also present.
