Synthesis of thiomolybdenyl complexes with [Mo2(S)2(O)2]2+ cores and substitutionally labile ligands. Crystal and molecular structure of the tris(dimethylformamide)dioxotetrasulfidodimolybdenum complex

[Mo12S12O12(OH)12(H2O)6]: A Cyclic Molecular Cluster Based on the [Mo2S2O2]2+ Building Block

“…The first method for introducing sulfur into a Keggin-type polyoxoanion was illustrated by the synthesis of a-[PW 11 NbSO 39 ] 4À , by selective substitution of the terminal oxygen atom of an NbO group by a sulfur atom, and its subsequent characterization. [8] The second technique was the stereospecific addition of an [Mo 2 S 2 O 2 ] 2 fragment to the cavity-containing polyanion g-[SiW 10 O 36 ] 8À .…”

“…[10,11] The selfcondensation reaction was performed by controlled addition of potassium hydroxide to an aqueous solution of the building opinion, these strategies will play a significant role in the development of catalysts and absorbents through the use of highly specialized and dedicated multifunctional units for sample preparation and identification/characterization, and through operation with a minimum of manual intervention. The [Mo 2 S 2 O 2 ] 2 unit was first prepared by selective oxidation of the terminal S 2 ligands of [(S 2 )MoO(m 2 -S) 2 MoO(S 2 )] 2À with iodine.…”

[Mo12S12O12(OH)12(H2O)6]: ein cyclischer molekularer Cluster aus [Mo2S2O2]2+-Baueinheiten

“…[ 2 MoO(S 2 )] 2À mit Iod synthetisiert. [10,11] Dazu wird der pH-Wert der wäûrigen Lösung der Baueinheiten durch kontrollierte Zugabe von Kaliumhydroxid erhöht. Dies führt zur Selbstkondensation der Baueinheiten und liefert die Titelverbindung in Form von blaûgelben Kristallen, die röntgenstrukturanalytisch charakterisiert werden konnten.…”
