“…The isostructural bis(n-propylammonium) tetrasulfidometalates crystallize in the centrosymmetric orthorhombic space group Pnma and the structure consists of two crystallographically independent organic cations and a [MS 4 ] 2À with the cations and anions located on mirror planes, resulting in two identical M-S distances in these compounds. This same structural feature of anion and cations lying on mirror planes is observed in K þ , Rb þ , Cs þ , ammonium and methylammonium [MS 4 ] 2À compounds [26,27,[29][30][31][32][33][34][35][36][37], all of which crystallize in the orthorhombic space group Pnma and exhibit two identical M-S distances (table 1). In the bis(alkylammonium) tetrasulfidometalates, the structures of the bis(methylammonium) [29,30] and bis(n-propylammonium) [27] compounds were reported by us.…”

“…As part of our research in this area, we are investigating the synthesis, spectral characteristics, thermal properties, and structural aspects of tetrasulfido compounds of Mo and W [6][7][8][9][10]. The research has resulted in a rich structural chemistry of the tetrahedral [MS 4 ] 2À (M ¼ Mo, W) compounds charge balanced by organic ammonium cations [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28].…”

“…The band at 474.5, 474.1 and 481.6 cm −1 for I, II and III could be attributed to the presence of (Mo S) asymmetric vibration due to MoS 4 2− moiety. The infrared spectrum of Mo 2 S 4 2+ core was reported to correspond to (Mo S) at 523 cm −1 and a series of weaker bands between 496 and 296 cm −1 differing substantially from the infrared spectrum exhibited by Mo 2 S 12 2− anion [1,10]. a band [22] at 408 cm −1 and the same band for MoO 2 S 2 2− occurs [23] at 466 cm −1 .…”

“…The importance of molybdenum-sulfur chemistry in industrial catalysis and bioinorganic chemistry has stimulated recent interest inducing broad research in these fields [1][2][3][4]. Many of the new sulfidometal complexes prepared and characterized, in the recent years, have revealed novel structures and bonding modes.…”

“…[4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] Hydrated salts of organic amines exhibit interesting structural features such as a bilayer in 2-aminoanilinium perchlorate monohydrate, 12 sulfate anion helices in ophenylenediammonium sulfate sesquihydrate, 13 a onedimensional polymeric chain of water in [(3-aba) (dabcoH)(H 2 O) 2 ] (3-aba = 3-aminobenzoate; dabco = 1,4-diazabicyclo [2,2,2]octane), 14 a water bridged cyclic dibromide unit in (dbtmen)Br 2 •2H 2 O (dbtmen = N,N′dibenzyl-N,N,N′,N′-tetramethylethylenediammonium), 15 a spiral-like anionic water chain containing a water dimer in (dbtmen)Cl 2 •3H 2 O 16 , water pipe held up by a polyoxometalate supported transition metal complex 17 and linear water dimer in an alkaline earth 4nitrobenzoate. 18 In our research, we have investigated the supramolecular structure of compounds containing tetrahedral anions like tetrasulfidotungstate [19][20][21][22] [WS 4 ] 2− , tetrasulfidomolybdate [23][24][25] [MoS 4 ] 2− , monooxidotrisulfidotungstate 26 [WOS 3 ] 2− , etc. charge balanced by organic ammonium cations.…”
