摘要

Two new phosphoric triamides, N-(2-chloro-5-fluorobenzoyl)-N,N ''-bis(morpholin-4-yl)-phosphoric triamide, (2-Cl,5-F-C6H3C(O)NH)P(O)(NC4H8O)(2), 1, and N,N-dibenzyl-N ''-(2-chloro-5-fluorobenzoyl)-N,N '-diethylphosphoric triamide, (2-Cl,5-F-C6H3C(O)NH)P(O)(N(C2H5)(CH2C6H5))(2), 2, were synthesized and characterized by H-1-, C-13-, P-31-, F-19-NMR and IR spectroscopies and single-crystal X-ray diffraction analysis. Different orientations of P(O) versus NH, anti in 1 and syn in 2, lead to different hydrogen bond patterns, mediated by N-H center dot center dot center dot O, as a linear arrangement forming a C(4) motif and a dimeric aggregate with an R-2(2)(8) ring motif, respectively. The crystal packing of both compounds present a three-dimensional supramolecular assembly, made by the cooperation from weak intermolecular interactions, C-H center dot center dot center dot O and C-H center dot center dot center dot pi, for 1 and 2, and pi center dot center dot center dot pi for 2. Hirshfeld surface analysis demonstrates that the HH contacts are decisive for both structures with contribution portions of 39.1% for 1 and 49.6% for 2. The O center dot center dot center dot H/H center dot center dot center dot O (1: 24.4% and 2: 9.6%) contacts are the characteristic intermolecular interactions, showing a pair of sharp spikes; while C center dot center dot center dot H/H center dot center dot center dot C contacts (1: 11.3% and 2: 21.7%), associated to the pi center dot center dot center dot H/H center dot center dot center dot pi interactions, can be illustrated as wings in the corresponding fingerprint plots. The CC contacts are revealed for 2 (1.6%), associated to pi center dot center dot center dot pi interaction observed in the X-ray analysis.

HIRSHFELD表面分析表明,HH触点对于两个结构的贡献部分为39.1%,对于2的贡献部分为39.1%,为2. O中心点中心点中心点H / H中心点中心点中心点O(1:24.4%和2:9.6%)触点是特征分子间相互作用,显示一对尖锐的尖峰;虽然C中心点中心点中心点H / H中心点中心点COT中心点C触点(1:11.3%和2:21.7%),与PI中心点中心DOT中心点H / H中心点中心DOT中心点相关联PI交互,可以在相应的指纹图中被说明为翼。 CC触点显示为2(1.6%),与在X射线分析中观察到的PI中心点中心点中心点PI相互作用相关。
