Abstract:
The synthesis and characterization of the bis(alkylammonium) tetrasulfidometalates, (EtNH(3))(2)[MS(4)] (M = W 1, Mo 2), [BuNH(3)](2)[MS(4)] (M = W 3; Mo 4) and (Et-enH(2))[WS(4)] 1-en (Et-en = N-ethylethane-1,2-diamine), are reported. Compound 1 crystallizes in the centrosymmetric orthorhombic space group Pnma and its structure consists of discrete slightly distorted tetrahedral [WS(4)](2-) of m symmetry, separated by two crystallographically independent (EtNH(3))(+) ions located on mirror planes. The carbons of one ethylammonium are disordered. Compound 1-en crystallizes in the centrosymmetric orthorhombic space group Pbca with all atoms situated in general positions. Its structure consists of discrete (Et-enH(2))(2+) and a slightly distorted tetrahedral [WS(4)](2-) with the cations and anions linked by several weak hydrogen bonds.
