Coordination-Induced Condensation of [Ta6O19]8–: Synthesis and Structure of [{(C6H6)Ru}2Ta6O19]4–and [{(C6H6)RuTa6O18}2(μ-O)]10−

“…8 The half-sandwich fragment {(arene)Ru} 2+ belongs to the family of the isolobal fragments d 0 -fac-{MO 2 (OR)} + and d 6 -fac-{ML 3 } (ML 3 = M(CO) 3 (M = Mn, Re), (arene)Ru, CpRh), among which Ru(II) monoarene complexes represent one of the most popular building blocks for grafting of a noble metal (Ru) to a POM. 9 It coordinates to [V 6 O 19 ] 8− and stabilizes it by coordination; 10 3 ) 2 ] 2− were isolated by varying the reaction conditions and arenes. 14 18 The organometallic moiety attaches regiospecifically to the {Nb 3 O 9 } group.…”

High oxidation state organomolybdenum and organotungsten chemistry in protic environments

“…Compound 12 ], were also obtained [170]. More recently, compounds [(( 6 -arene)Ru) 4 (WO) 4 (-O) 12 ] (arene = C 6 Me 6 , pMeC 6 H 4 iPr) where obtained similarly from Na 2 WO 4 and [( 6 -arene)RuCl 2 ] 2 , although the reaction was conducted in acetonitrile [171].…”

Rational Synthesis and Characterization of the Mixed-Metal Organometallic Polyoxometalates [Cp*MoxW6–xO18]− (x = 0, 1, 5, 6)

“…[25][26][27][28][29][30][31][32][33][34] The use of hydrothermal methods starting from elementary bricks is another alternative strategy, the outcome of which is however largely affected by serendipity. 31,35 POMs grafted with organometallic fragment have attracted interest [36][37][38][39][40][41][42] 42 Recently, we have reported the use of Cp*2M2O5 (M = Mo, W), compounds that are stable in air and in aqueous solution in the entire pH range, 43 in combination with the inorganic salts Na2M'O4 (M' = Mo, W) in a 1:4 ratio, as precursors of the hexanuclear organometallic polyoxometallic complexes Cp*2MoxW6-xO17 (x = 0, 2, 4, 6) in a selective, high-yielding, room temperature aqueous reaction. 44,45 The formula of these compounds may also be written as [ [46][47][48] two adjacent metallic atoms bear a Cp* ligand in place of a terminal oxido ligand, leading to a neutral compound.…”
