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

Abstract

The P atom in the title mol­ecule, C10H23ClN3O2P, 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(CH3)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.
