- W2326571049 abstract "Reduction of TaCl5 with either Ga or Ga2Cl4, in the presence of NaCl, in a sealed borosilicate glass ampule at 500 °C, followed by aqueous Soxhlet extraction and treatment with SnCl2 and hydrochloric acid, yielded Ta6(μ-Cl)12Cl2(OH2)4·4H2O in 92% (Ga) or 96% (Ga2Cl4) yield. Ga2Cl4, a probable intermediate in the Ga-based reduction, is a more convenient reductant than Ga because it is readily dispersed in the reaction mixture, and these mixtures do not require homogenizations in order to afford high yields. Ta6(μ-Cl)12Cl2(OH2)4·4H2O was converted by ligand exchange to the first tetraalkylammonium derivative, [N(CH2Ph)Bu3]4[Ta6(μ-Cl)12Cl6], of the reduced cluster core Ta6(μ-Cl)122+, in 88% yield. [N(CH2Ph)Bu3]4[Ta6(μ-Cl)12Cl6] crystallizes from 1,2-dichloroethane/toluene mixtures in two crystalline morphologies, a nonsolvated cubic form and a solvated needle form. The solid-state molecular structures of both crystalline morphologies of [N(CH2Ph)Bu3]4[Ta6(μ-Cl)12Cl6] consist of octahedral, 16 VEC hexatantalum cluster anions with an average Ta−Ta distance of 2.900[2] Å, a Ta−Cl(bridge) distance of 2.463[2] Å, a Ta−Cl(terminal) distance of 2.567[5] Å, and a Ta−Cl−Ta angle of 72.1[1]° for the cubic form, and for the solvated needle morphology, an average Ta−Ta distance of 2.900[1] Å, a Ta−Cl(bridge) distance of 2.461[1]Å, a Ta−Cl(terminal) distance of 2.567[3] Å, and a Ta−Cl−Ta angle of 72.19[7]°." @default.
