The new compound N-(3-nitrobenzoyl)-N',N''-bis(tert-butyl)phosphoric triamide was synthesized by reacting 3-nitrobenzoyl phosphoramidic dichloride and tert-butyl amine, and characterized by multinuclear (1H, 13C and 31P) NMR and FTIR spectroscopy techniques. Structural and conformational properties were analyzed using single-crystal X-ray diffraction, vibrational spectra and theoretical calculations. The crystal structure contains three symmetry-independent disordered molecules, connected via intermolecular N-HO=P and N-HO=C hydrogen bonds to form a centrosymmetric hexameric chain extended along the [2,1,] direction. The disorder is mainly caused by rotation of the tert-butyl groups around the C-N bonds.
Rentgenová difrakce, vibrační spektra a teoretické výpočty. Krystalová struktura obsahuje tři symetricky nezávislé molekuly s disordrom spojené mezimolekulárními N-HO=P a N-HO=C vodíkovými můstky. Tímto způsobem tvoří centrosymetrické hexamerální prodloužení řetězce ve směru [2,1,]. Disorder je způsobený hlavně rotací skupin terciálních butylů okolo C-N vazby.
