Mr. Churchill et al., CRYSTAL AND MOLECULAR-STRUCTURE OF [(C6H5)(2)P(=O)(CH2CH2N(CH3)(3))(-]()][I), Journal of chemical crystallography, 26(11), 1996, pp. 747-752
The title compound crystallizes in the centrosymmetric triclinic space
group P (1) over bar with Z = 4. The crystallographic asymmetric unit
contains two independent cations; interatomic distances within these
include P=O = 1.47(1) and 1.47(1)Angstrom, P-C6H5 = 1.78(2)-1.81(1)Ang
strom and P-CH(2)CH(2)NMe(3)(+) = 1.80(1) and 1.81(1)Angstrom. The pho
sphine oxide moiety is involved in intermolecular hydrogen bonding (O
... H-C, with O .. H greater than or equal to 2.42 Angstrom) and the i
odide is involved in I ... H-C contacts with I ... H greater than or e
qual to 3.10 Angstrom.
