N,N '',N '',N ''''-Tetrakis(2-methylphenyl)oxybis(phosphonic diamide): a redetermination at 150 K with Mo K alpha radiation.

Popis výsledku v původním jazyce

The structure of the title compound, C(28)H(32)N(4)O(3)P(2), has been redetermined at 150 K, with much improved precision. The structure and molecular packing of the title compound was previously determined using Cu K alpha radiation, with an R value of0.0933 [ Cameron et al. (1978). Z. Naturforsch. Teil B, 33, 728-730]. The c-axis length in this structure [13.8401 (8) angstrom] is almost half that reported in the original study. In the title compound, two (C(6)H(4)(2-CH(3))NH)(2)P(O) units are bridgedvia an O atom [P-O-P = 133.31 (11)degrees]. The P atoms adopt a slightly distorted tetrahedral coordination geometry. In the crystal, molecules are linked via N-H center dot center dot center dot OP hydrogen bonds into extended chains parallel to the caxis. An intramolecular N-H center dot center dot center dot O=P hydrogen bond is also found in the molecule.
