Abstract: The reaction of (NH4)2[MS4] (M = W, Mo) with n-propylamine (CH3-CH2-CH2-NH2) results in the formation of bis(n-propylammonium) tetrasulfidometalates (CH3-CH2-CH2-NH3)2[MS4] (M = W (1); Mo (2)). Both compounds have been characterized by elemental analysis, IR, Raman and UV-vis spectra and crystal structures. Compounds (1) and (2) are isostructural and crystallize in the centrosymmetric orthorhombic space group, Pnma. The structure consists of discrete slightly distorted tetrahedral tetrasulfidometalate [MS4]2- anions of m symmetry, separated by two crystallographically independent n-propylammonium cations located on mirror planes. The carbon atoms of the organic cations are disordered. A comparative study of twelve tetrasulfidometalates crystallizing in the orthorhombic space group Pnma is presented.
