O,O'-Di-p-tolyl-pyrophospho-ric Bis-(dimethyl-amide)
Overview
Affiliations
The title compound, C(18)H(26)N(2)O(5)P(2), was obtained accidently from the reaction between N,N-dimethyl-phospho-ramido-chloridic acid 4-methyl phenyl ester, NaNO(2) and 18-crown-6 in acetonitrile under reflux conditions. The asymmetric unit contains one half-mol-ecule, the complete mol-ecule being generated by crystallographic twofold symmetry, with the bridging O atom lying on the rotation axis. The P atoms exhibit a tetra-hedral coordination and are bridged via one O atom [P-O-P angle = 130.00 (19)°].
