✦ Synopsis

The crystal structure of 1,2-phenylene phosphorochloridate has been determined. X-Ray irradiation of these crystals, at low temperature, leads to the formation of a radical exhibiting hyperfine structure with P and CI nuclei. The corresponding ESR tensors are obtained, and they show that this radical is a phosphoranyl radical adopting a slightly distorded u* structure. The same species could be produced in frozen solution, its hyperfine tensors are, then, more in accordance with a trigonal-bipyramid structure. The effects of the host matrix on the stabilization of the structure of phosphoranyl are investigated.

## Abstract When a 1° or 2° alcohol solution of benzophenone and 2,4‐pyridinedicarbonitrile (**1**) is irradiated, the 2,4‐dicyanopyridinyl radical (**2**) is formed immediately. When the irradiation is performed in the cavity of an ESR spectrometer, the spectrum amplitude increases to a near stead
