Abstract

A method for synthesizing N,N-diethyl-P-methylphosphonamidic chloride via the reaction of methylphosphonic dichloride with diethylamine is presented. The structures of methylphosphonic dichloride and N,N-diethyl-P-methylphosphonamidic chloride were confirmed using single-crystal X-ray diffraction, as well as nuclear magnetic resonance and infrared spectroscopies. The formation of the 3D crystal structure is facilitated to the multiple nonclassical hydrogen bonds formed between the oxygen atom of the P=O group and the hydrogen atoms of the P–CH₃ methyl group.

期刊介绍： The Journal of Molecular Structure is dedicated to the publication of full-length articles and review papers, providing important new structural information on all types of chemical species including: • Stable and unstable molecules in all types of environments (vapour, molecular beam, liquid, solution, liquid crystal, solid state, matrix-isolated, surface-absorbed etc.) • Chemical intermediates • Molecules in excited states • Biological molecules • Polymers. The methods used may include any combination of spectroscopic and non-spectroscopic techniques, for example: • Infrared spectroscopy (mid, far, near) • Raman spectroscopy and non-linear Raman methods (CARS, etc.) • Electronic absorption spectroscopy • Optical rotatory dispersion and circular dichroism • Fluorescence and phosphorescence techniques • Electron spectroscopies (PES, XPS), EXAFS, etc. • Microwave spectroscopy • Electron diffraction • NMR and ESR spectroscopies • Mössbauer spectroscopy • X-ray crystallography • Charge Density Analyses • Computational Studies (supplementing experimental methods) We encourage publications combining theoretical and experimental approaches. The structural insights gained by the studies should be correlated with the properties, activity and/ or reactivity of the molecule under investigation and the relevance of this molecule and its implications should be discussed.
