Low-Temperature Synthesis of Diamminesodium (1+) Triamminesodium (1+) Trithioantimonate (3-) Ammoniate (1:2:1:2) ([Na(NH_3)_3]_2[Na(NH)_3]_2SbS_3.2NH_3), A Solvated Neutral Sodium Trithioantimonate (3-) (3:1) Na_3SbS_3)Ion Complex

摘要

A solution of sodium in liquid ammonia reacts with Sb_2S_3 to form large colorless crystals of the composition Na_3SbS_3.10nh_3. The trigonal-pyramidal SbS_3~(3-) anion is ion-paired with three Na~+ counter ions, the coordination spheres of which are completed by eight ammine ligands. The resulting neutral [Na(NH_3)_3]_2-[Na(NH_3)_2]SbS_3 molecules crystallize together with two ammonia molecules of solvation in the space group P2_1/c (a = 9.828(2), b = 6.0702(4), c = 33.4377(6) A, #beta# = 91.362(7), V = 1994.2(5) A~3, Z = 4).
