X-ray crystallography and NQR spectroscopy have been jointly used to study CCl3X-hexakis(phenylthio)benzene (HPTB) (X=Cl, Br, CH3, CN, NO2, H) clathrates. The crystal of the non-clathrated HPTB is triclinic, [Formula: see text] a = 9.5614(7), b = 10.

The diphenylphosphino radical, (C6H5)2P, has been observed at room temperature in X-irradiated single crystals of triphenylphosphine oxide and diphenylphosphine sulphide and in ultra-violet irradiated polycrystalline diphenylphosphine at 77 K. The is

Previous theoretical estimates of the coupling between an electron in a carbon 2p π orbital and a β-proton, as in the ethyl radical, have been based on an incorrect model of hyperconjugation. A correct model is proposed and the various contribution

The E.S.R. spectra of phosphorus-centred radicals formed in the X-irradiation of single crystals of methylene diphosphonic acid are reported. The radicals are identified as phosphoranyl radicals, (HO)2(O)P-CH2-P(OH)3 and the tricoordinated species OP

ESR spectra of x‐irradiated single crystals of (C6H5)3AsO were investigated. One of the two radical species trapped in the crystal was identified as being the diphenylarsino radical (C6H5)2Ȧs. The g and 75As magnetic coupling tensors were determin

X-irradiation of single crystals of triphenylgermane yields the triphenylgermyl radical (C 6 H 5 ) 3 Ge. The 73 Ge hyperfine coupling parameters show that, as expected, the radical is non-planar and similar to (C 6 H 5 ) 3 Si and (C 6 H 5 ) 3 P + . Q
