The reaction of P3N3Cl6 (1) with heptamethyldisilazane in the molar ratio 1:1 leads to the formation of 2,4,4,6,6-pentachloro-N-methyl-N-(trimethylsilyl)cyclotriphosphazen-2-amine, P3N3Cl5{N(CH3)[Si(CH3)3]} (2). Compound 2 was characterized by elemental analysis and spectroscopically. Molecular and crystal structures of 2 were determined by X-ray diffraction. 2 is monoclinic, space group P21/n. Experimental data were compared with results of DFT calculations.
