Full TextAbstract
In continuation of the previous works on synthesis and structure determination of racemate mixed-amidophosphinates with (N2)P(O)(O)(N1) skeleton [1-4], two new rac-XP(O)(OC6H5)(NHC6H4-p-CH3) [X = NHC5H9 (1) and N(4-CH3C5H9) (2)] mixed amidophosphinates were synthesized and characterized by 31P{1H}, 13C, 1H NMR spectroscopy and single crystal X-ray determination. The P atom in each molecule is in a distorted tetrahedral environment with two different amido groups bonded to P atom [1-4]. The asymmetric unit of 1 and 2 are composed of one molecule and two symmetrically independentmolecules, respectively. Among the two independent molecules in the asymmetric unit of (2), one C6H5O group was found to be disordered. In the structures, the oxygen atom of C6H5O group and the nitrogen atoms bonded to P do not take part in hydrogen bonding as an acceptor; whereas, the oxygen atom of phosphoryl acts as a double-H bond acceptor. Adjacent molecules are linked via N—H•••O=P hydrogen bonds in a linear arrangement, parallel to [010] for (1) and [100] for (2).
