Crystal Structure of Bis[hexakis(dimethylamino)cyclotriphosphonitrilium] Tetrachlorocobaltate(II)
Keyword(s):
Crystals of the title compound, [N3P3(NMe2)6H]2CoCl4, are orthorhombic, a = 34.623, b = 13.964, c = 10.486 Å, Z = 4, space group P212121. The structure was determined by Patterson and electron-density methods and refined by full-matrix least-squares procedures to R = 0.088 for 2178 observed reflexions. Both rings are slightly non-planar, with three distinct pairs of NP bonds: commencing at the protonated nitrogen atom, 1.68, 1.56, and 1.58 Å. The CoCl42− ion is tetrahedral and is hydrogen bonded to both rings, N—H … Cl = 3.32, 3.36 Å.
