The P atom in the title mol-ecule, C(12)H(26)N(3)OP, has a distorted tetra-hedral configuration: its bond angles lie in the range 101.1 (2)-119.1 (2)°. The P-N bonds to the two cyclo-pentyl-amido moieties are significantly different [1.619 (4) and 1.643 (4) Å], with the shorter bond related to an anti orientation of the lone electron pair of the corresponding N atom relative to the P=O bond. Th...

In the title compound, C(14)H(18)N(3)OP, a crystallographic mirror plane bis-ects the mol-ecule (the C,N,C atoms of the dimethyl-amido moiety and the P=O unit lie on the mirror plane). The P atom has a distorted tetra-hedral geometry; the bond angles at P are in the range 98.98 (11)-115.28 (7)°. In the crystal, the O atom of the P=O group acts as a double hydrogen-bond acceptor for two symmetry...
