N,N′-Di-tert-butyl-N′′-(2-chloro­acet­yl)phospho­ric triamide

The P atom in the title mol­ecule, C(10)H(23)ClN(3)O(2)P, has a distorted tetra­hedral coordination. In the C(O)NHP(O) unit, which has syn-oriented phosphoryl and N—H groups, the P—N bond of 1.703 (2) Å is longer and the O—P—N angle of 103.86 (7)° is contracted compared with the respective values in the two P(O)NHC(CH(3))(3) units [P—N = 1.632 (2) and 1.624 (2) Å; O—P—N = 116.80 (8) and 115.32 (8)°]. In the crystal, each mol­ecule is hydrogen bonded to two adjacent mol­ecules via N—H⋯O hydrogen bonds, forming a linear sequence of alternating R (2) (2)(8) and R (2) (2)(12)/R (2) (1)(6)-fused rings along [010]. The O atom of the carbonyl group acts as a double H-atom acceptor.
