W. Bensch et al., Solvothermal synthesis of [Ni(C4H13N3)(2)](2)Sb4S8: the first compound with a cyclic [Sb4S8](4-) anion, CHEM COMMUN, (5), 2001, pp. 477-478
Under mild hydrothermal conditions the novel thioantimonate(iii) [Ni(C4H13N
3)(2)](2)Sb4S8 was synthesised using elemental nickel, antimony and sulfur;
the structure is composed of cyclic isolated [Sb4S8](4-) anions and [Ni(C4
H13N3)(2)](2+) cations.
