Reactions of the Cycloheptatrienyl Complexes [η7-C7H7W(CO)3]BF4 and η7-C7H7Mo(CO)2Br with Neutral Ligands and the Electrochemical Reduction of the Wolfram Complex Compounds of the type [η7-C7H7M(CO)2L][BF4] (L = P(C6H5)3, As(C6H5)3, Sb(C6H5)3 for M = W and L = N2H4 for M = Mo) were synthesized and characterisized. The iodide η7-C7H7W(CO)2I reacts with the diphosphine ((C6H5)2PCH2)2 to give the trihapto complex η3-C7H7 W(CO)2I((C6H5)2PCH2)2. In the case of η7-C7H7Mo(CO)2 Br reaction with hydrazine leads to the substitution product [η7-C7H7 Mo(CO)2N2H4]⊕, which can be stabilized by large anions. The binuclear complex [C7H7W(CO)3]2 has been synthesized electrochemically. 相似文献

Molecular and Crystal Structures of (CO)4W(μ-S-t-C4H9)2W(CO)4, η7-C7H7W(μ-SC6H4CH3)3W(CO)3 and η7-C7H7W(μ-S-n-C4H9)3W(CO)(μ-S-n-C4H9)2W(CO)4 The molecular structures of the two binuclear complexes (CO)4W(μ-S-t-C4H9)2W(CO)4 and η7-C7H7W(μ-SC6H4CH3)3W(CO)3 and of the tungsten cluster η7-C7H7W(μ-S-n-C4H9)3W(CO)-(μ-S-n-C4H9)2W(CO)4 respectively are described. In the nonlinear trinuclear cluster the central tungsten atom is connected to the two tungsten atoms by two and three μ-S-n-C4H9 bridges respectively and additionally by one W? W bond each. The coordination sphere of the W atoms is completed by a η7-C7H7 ring and four CO groups respectively; the central tungsten carries an additional CO group. 相似文献

The tetranion ligand η7-C2B10H124− has been observed for the first time in 1 , which was obtained from the reaction of o-C2B10H12 with excess K metal followed by treatment with UCl4. As shown in the picture (without K cations and coordinated THF molecules), 1 is a centrosymmetric dimer with a bent sandwich structure. 相似文献
