Synthesis and Characterization of the Nitrogen‐Centered Trigonal Prismatic Clusters [W6NCl18]n− (n=1–3)

Central effects: Molecular salts, including Na[W6NCl18], (Bu4N)[(Ph3P)2N][W6NCl18], and (Bu4N)3[W6NCl18]⋅MeCN, were prepared that contain [W6NCl18]n− (n=1–3) clusters (for an example, see picture of [W6NCl18]−), reminiscent of a fragment of WN. Cyclic-voltammetric studies indicate the accessibility of species possessing 24–27 {W6N}-based valence electrons.
