medium-sized rings [PCl2N]m have been characterized by electrospray ionization–mass spectroscopy (ESI-MS), their 31P chemical shifts have been reassigned, and their T1 relaxation times have been obtained. Crystallographic data has been recollected for [PCl2N]5, and the crystal structures of [PCl2N]6, and [PCl2N]8 are reported. Halogen-bonding interactions were observed in all the crystal structures of cyclic

The cyclic chlorophosphazenes NnPnCl2n(n= 3–6) are fluorinated by a mixture of SbF3 and SbCl5 to give either the monofluoro-compound or, depending on the reagent ratio, mixtures of non-geminal chloride fluorides. The n.m.r, parameters of the monofluorides show similar ring-size effects to the monochlorofluorocyclophosphazenes.
通过SbF 3和SbCl 5的混合物将环状氯代磷腈N n P n Cl 2 n(n = 3–6)氟化,得到单氟化合物,或者取决于试剂的比例,得到非双基氯氟化物的混合物。一氟化物的nmr参数显示出与一氯氟环磷腈类似的环尺寸效应。
