Abstract: | Substituted Halocarbonyl Metallates of Chromium, Molybdenum, and Tungsten. IV. Crystal Structure of Tetramethylammonium Chloropentacarbonyltungstate The 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. |
