Abstract

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-equivalent N-H⋯O hydrogen bonds, building [001] chains containing R(2) (1)(6) loops.

摘要

在标题化合物C₁₄H₁₈N₃OP中，一个晶体学镜面将分子平分（二甲基氨基部分的C、N、C原子以及P=O单元位于镜面上）。P原子具有扭曲的四面体几何构型；P原子处的键角范围为98.98 (11)°至115.28 (7)°。在晶体中，P=O基团的O原子作为两个对称等效的N-H⋯O氢键的双氢键受体，形成包含R₂²⁽⁶⁾环的[001]链。
