The new thioantimonate(V) (C3H10N)[NiSbS4(C6H18N4)].
Turquoise crystals of the title salt, propylammonium di-mu-thio-1:2 kappa(4)S-dithio-2 kappa(2)S-tris(2-aminoethyl)amine-1 kappa(4)N-antimony(V)nickel(II), (C(3)H(10)N)[NiSbS(4)(C(6)H(18)N(4))] or [PAH][Ni(tren)SbS(4)] [where tren is tris(2-aminoethyl)amine and PA is propylamine], were synthesized under solvothermal conditions by reacting [Ni(tren)(2)]Cl(2), Sb and S in a solution of PA. The Ni(II) ion is octahedrally surrounded by four N atoms of the tetradentate tren molecule and by two S atoms of the tetrahedral [Sb(V)S(4)](3-) anion, thus forming the anionic [Ni(tren)SbS(4)](-) part of the compound. Charge balance is achieved through the PAH(+) cation. An extended intermolecular hydrogen-bonding network is observed between the anion and the cation.
