摘要：

Refluxing WCl4(PMe3)(3) under a nitrogen atmosphere in the presence of two equivalents of sodium amalgam leads to a reduction to the W(II) complex [cis, mer-WCl2(PMe3)(3)](2)N-2 (1), which can be converted to [mer, trans-WCl3(PMe3)(2)](2)N-2 (2) via appropriate oxidation/chlorination. Structural data have been obtained for both complexes, and demonstrate significantly increased steric crowding in 1 due to PMe3/PMe3 interactions. The N-N bond distances in the two compounds are similar, at 1.279(4) and 1.243(18) angstrom, respectively. (C) 2009 Elsevier B. V. All rights reserved.
