We report the crystal structure of the rubidium tetrasulfide‐ammoniate(3) Rb(18‐crown‐6)RbS 4 ·3NH 3 (18‐crown‐6 = 1,4,7,10,13,16‐hexaoxacyclooctadecan), which formed as a byproduct from an equimolar reaction of elemental rubidium with SiS 2 and 18‐crown‐6 in liquid ammonia. Single crystals were isolated and characterized by low temperature X‐ray structure analysis. Rb(18‐crown‐6)RbS 4 ·3NH 3 crystallizes in the chiral space group P 2 1 2 1 2 1 with a = 8.2936(6) Å, b = 16.3880(12) Å, c = 18.3203(14) Å, V = 2490.0(3) Å 3 and Z = 4 as amber, prism shaped crystals. The ammoniate contains the typically chain‐like tetrasulfide anion S 4 2– , rubidium–sulfur contacts lead to one‐dimensionally infinite 1 ∞ [{Rb(18‐crown‐6)(NH 3 )} 2 {Rb 2 ( μ ‐NH 3 ) 4 }{S 4 } 2 ] chains.
