Bis[benzyl(methyl)ammonium] tetrathiomolybdate(VI)

Abstract

Key indicators: single-crystal X-ray study; T = 298 K; mean (C-C) = 0.009 Å; R factor = 0.050; wR factor = 0.100; data-to-parameter ratio = 17.3.The title compound, (C 8 H 12 N) 2 [MoS 4 ], was synthesized by the aqueous reaction of ammonium tetrathiomolybdate with benzyl(methyl)amine in a 1:2 molar ratio. The structure consists of a slightly distorted tetrahedral [MoS 4 ] 2À dianion and two crystallographically independent benzyl(methyl)ammonium cations, with all atoms located in general positions. The cations and anions are linked by weak N-HÁ Á ÁS and C-HÁ Á ÁS interactions, the strength and number of which can explain the observed Mo-S bond distances.

“…Previous reports give details of the structural characterization of several organic ammonium tetrasulfidomolybdates derived from chiral amines , diamines (Srinivasan et al, 2001;Srinivasan, Dhuri et al, 2005;, triamines (Srinivasan, Dhuri et al, 2007), cyclic amines , a tetraamine (Srinivasan et al, 2004), a primary amine (Srinivasan, Nä ther, Naik & Bensch 2006) and a secondary amine (Srinivasan, Girkar & Raghavaiah 2007). The title compound is isotypic with the corresponding W analogue (C 3 H 10 N) 2 [WS 4 ] (Srinivasan, Nä ther, Dhuri & Bensch 2006).…”

“…Previous reports give details of the structural characterization of several organic ammonium tetrasulfidotungstates containing organic cations derived from chiral amines (Srinivasan, Naik et al, 2007), diamines (Srinivasan et al, 2002;2003a;Srinivasan, Nä ther et al, 2006a), triamines (Srinivasan, Nä ther et al, 2006b), cyclic amines (Srinivasan et al, 2003b;Srinivasan, Naik et al, 2006) and a tetraamine (Srinivasan et al, 2005). The title compound is isotypic with the corresponding Mo analogue (C 8 H 12 N) 2 [MoS 4 ] (Srinivasan, Girkar & Raghavaiah 2007).…”

“…The title compound is isostructural with the corresponding Mo analogue (C 8 H 12 N) 2 [MoS 4 ] (Srinivasan, Girkar & Raghavaiah 2007). The structure of (I) consists of a discrete tetrahedral [WS 4 ] 2ion and two crystallographically independent benzyl(methyl)ammonium cations ( Fig.…”

Synthesis and characterization of bis(alkylammonium) tetrasulfidometalates

“…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].…”
