Reference of 37366-09-9. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer. In a document type is Article, introducing its new discovery.
A family of {Ru(arene)}2+-containing heteropolytungstates of general formula [{Ru(L)}2(alpha-XW11O39) 2WO2]m- (L = benzene, p-cymene; X = Ge IV, SiIV, m = 10; X = BIII, m = 12) has been prepared in aqueous acidic medium (pH ? 4). The 1:1 interaction of [Ru(C 6H6)Cl2]2 or [Ru(p-cymene)Cl 2]2 with [beta2-GeW11O 39]8- led to the formation of [{Ru(benzene)} 2(GeW11O39)2WO2] 10- (1) and [{Ru(p-cymene)}2(GeW11O 39)2WO2]10- (2), respectively. Replacing [beta2-GeW11O39]8- by [alpha-SiW11O39]8- resulted in [{Ru(benzene)}2(SiW11O39)2WO 2]10- (3) and [{Ru(p-cymene)}2(SiW 11O39)2WO2][SiW12O 40]0.512- (4), respectively. The reaction of [alpha-HBW11O39]8- with the respective {Ru(arene)}2+-containing precursors resulted in polyanions [{Ru(benzene)}2(HBW11O39)2WO 2]10- (5) and [{Ru(p-cymene)}2(HBW 11O39)2WO2]10- (6), respectively. Single-crystal XRD analysis of the hydrated salts of 1-6 revealed that these species comprise two Keggin fragments, [{Ru(L)}alpha-XW 11O39]6- (L = benzene, p-cymene; X = Ge IV, SiIV) for polyanions 1-4 and [{Ru(L)}alpha-HBW 11O39]6- (L = benzene, p-cymene) for 5 and 6, connected via a cis-dioxo {WO2}2+ unit. In addition, the heteropolytungstates were characterized by thermogravimetric analysis, IR spectroscopy, elemental analysis, and solution electrochemical studies. Copyright
