Centrosymmetric Dimmers of XC(O)N(H)P(O)[N(CH3)(C6H11)]2, (X=CF3,CCl3)

New phosphoramidate compounds with formula CCl3C(O)N(H)P(O)[N(CH3)(C6H11)]2 (1) and CF3C(O)N(H)P(O)[N(CH3)(C6H11)]2 (2) crystallized in monoclinic and triclinicspace groups P21/n (Z=4), Pī (Z=2) respectively. Unit cell dimensions are a = 10.1459(3)Å, b = 10.5493(3)Å, c = 20.3293(6)Å, β = 103.071(2)° and a =8.4051(4)Å, b = 10.9557(5)Å, c = 12.4462(9)Å, α = 106.370(3)°, β = 103.077(3)°, γ = 109.306(2)° at 203(2) K. Centrosymmetric dimmers of both compounds produced byN-H…O-P hydrogen bonds. Considering the weak C-H…O H-bonds in compound 1 and C-H…F in compound 2, both compounds appear as infinite chains in crystal lattice.
