Substituted Halocarbonyl Metallates of Chromium, Molybdenum, and Tungsten. IV. Crystal Structure of Tetramethylammonium ChloropentacarbonyltungstateThe structure of tetramethylammonium chloropentacarbonyltungstate has been determined from single crystal X-ray data. The compound crystallizes with four formula units in the monoclinic unit cell (space group P21/c) of the dimensions a = 1111.3(4) pm, b = 1110.3(4) pm c = 1204.1(3) pm, β = 99.63(3)°, V = 1464.8 × 106 pm3 (R = 0.028). The anion possesses approximately C4v symmetry with the principal interatomic distances d(W-C(cis)) = 203 pm, d(W-C(trans)) = 197 pm d(W-Cl) = 256.6 pm. No unusual contacts between cation and anion have been found.
Notes:
Die Struktur von Tetramethylammoniumchloropentacarbonylwolframat wurde röntgenographisch aus Einkristalldaten bestimmt. Die Verbindung kristallisiert mit vier Formeleinheiten in der monoklinen Elementarzelle (Raumgruppe P21/c) folgender Dimensionen: a = 1111,3(4) pm, b = 1110,3(4) pm, c = 1204,1(3) pm, β = 99,63(3)°, V = 1464,8 · 106 pm3 (R = 0,028). Das Anion besitzt annähernd C4v-Symmetrie mit d(W-C(cis)) = 203 pm, d(W-C(trans)) = 197 pm, d(W-Cl) = 256,6 pm. Zwischen Kation und Anion treten keine ungewöhnliche Kontakte auf.
