    Three new tetrathiomolybdates (pipH(2))[MoS4] (1), (trenH(2))[MoS4]. H2O (2) and [(prop)(4)N](2)[MoS4] (3) (pip = piperazine, tren = tris(2-aminoethyl)amine and prop = n-propyl) were synthesized and characterized by elemental ...
  • The correct formulation of the sulfur transfer reagent benzyltriethylammonium tetracosathioheptamolybdate 
    Srinivasan, B.R.; Dhuri, S.N.; Naik, A.R. (Tetrahedron Letters. 45; 2004; 2247-2249.)
    The recently reported sulfur transfer reagent benzyltriethylammonium tetracosathioheptamolybdate [(PhCH2)N(C2H5)3]6[Mo7S24] [Tetrahedron Lett. 2003, 44, 887] is correctly formulated as benzyltriethylammonium tetrathiomolybdate ...
  • Does an all-sulphur analogue of heptamolybdate exist? 
    Srinivasan, B.R. (Journal of Chemical Sciences. 116(5); 2004; 251-259.)
    The complexes [MoX4](2-) (M = Mo; X = O or S) exist as the monomeric tetrahedral species in aqueous alkaline solutions. Acidification of tetraoxomolybdate results in the condensation of the tetrahedral units via a series ...
  • Catalytic reduction of NOx by ammonia over nickel and lanthanum supported on zeolite 
    Salker, A.V.; Weisweiler, W. (Indian Journal of Chemistry Section A-Inorganic Bio-Inorganic Physical Theoretical and Analytical Chemistry. 43(6); 2004; 1167-1171.)
