Abstract
The synthesis and characterization of the bis(alkylammonium) tetrasulfidometalates, (EtNH3)2[MS4] (M = W 1, Mo 2), [BuNH3]2[MS4] (M = W 3; Mo 4) and (Et-enH2)[WS4] 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 [WS4]2− of m symmetry, separated by two crystallographically independent (EtNH3)+ 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-enH2)2+ and a slightly distorted tetrahedral [WS4]2− with the cations and anions linked by several weak hydrogen bonds.
