摘要：
The reaction of Ta6I14 with KNCS in acetonitrile in the presence of 24-dibenzo-crown-8 leads to dissolution of the tantalum iodide cluster to form the [Ta6I12(NCS)6]4− complex. By evaporation of the solution with the subsequent treatment of the precipitate with acetone and PPh4Br, dark green single crystals of the composition [K(C24H32O8)(CH3COCH3)]2(Ph4P)2[Ta6I12(NCS)6] CH3COCH3(1) are obtained with a yield of 29%. The product is characterized by elemental analysis, IR, and mass spectra. The crystal structure is determined by the X-ray diffraction analysis.
