摘要
Central effects: Molecular salts, including Na[W6NCl 18],(Bu4N)[(Ph3P)2N][W 6NCl18], and (Bu4N)3[W 6NCl18]·MeCN, were prepared that contain [W 6NCl18]n- (n = 1-3) clusters (for an example, see picture of [W6NC;18]-), reminiscent of a fragment of WN. Cyclic-voltammetric studies indicate the accessibility of species possessing 24-27 {W6N}-based valence electrons. (Figure Presented). © 2005 Wiley-VCH Verlag GmbH & Co. KGaA.
