Multinuclear magnetic resonance studies. Part 2. Diphosphanes and dithioxodi-.lambda.5-phosphanes. Aime, Silvio; Harris, Robin K.; McVicker, Elizabeth M.; Fild, Manfred (Sch. Chem. Sci., Univ. East Anglia, Norwich, Engl.). J. Chem. Soc., Dalton Trans., (21), 2144-53 (English) 1976. 1101-41-3 which is the cas registry number is also used here. CODEN: JCDTBI. DOCUMENT TYPE: Journal CA Section: 73 (Spectra by Absorption, Emission, Reflection, or Magnetic Resonance, and Other Optical Properties) 13C and 31P NMR spectra were obtained for 7 diphosphanes (RR1P)2 and 7 dithioxodi-.lambda.5-phosphanes [RR1P(:S)]2 (e.g. R = R1 = Et, Me2CH, Me3C, Ph; R = Me, R1 = Et, Me2CH, Me3C, Ph). Satellite resonances in 31P resonance due to 13C-contg. isotopomers were examd. P-P and P-C coupling consts. and 13C and 31P chem. shifts were detd. from the NMR data and PMR data where appropriate, and discussed in terms of steric interactions and stereoisomerism. Values of the P-P coupling consts. for both series of compds. increased as the size of the substituents increased, and this effect correlated with an increase in the P chem. shift. .

Synthesis and antimony-121 Moessbauer study of a number of organoantimony(III) compounds containing antimony-main Group V element bonds

Synthesis and antimony-121 Moessbauer study of a number of organoantimony(III) compounds containing antimony-main Group V element bonds. Stevens, John G.; Trooster, Jan M.; Martens, Henny F.; Meinema, Harry A. (Lab. Mol. Spectrosc., Univ. Nijmegen, Nijmegen 6525 ED, Neth.). Inorg.There are some reagents with their cas registry numbers 64482-70-8 and 1101-41-3 are used in this study. Chim. Acta, 115(2), 197-201 (English) 1986. CODEN: ICHAA3. ISSN: 0020-1693. DOCUMENT TYPE: Journal CA Section: 29 (Organometallic and Organometalloidal Compounds) Section cross-reference(s): 22 The prepn. of R2SbMR12 (I; R, R1 = Et, Ph; M = N, P, As) was examd. I (R = Et, Ph; M = N; R1 = Ph) were successfully prepd. Attempts to prep. phosphinostibines and arsinostibines failed and resulted in diphosphines, diarsines, and distibines. Only in the case of Ph2AsSbPh2 was an anal. pure product obtained. A series of Sb(III) compds. contg. Sb-main Group V element bonds was studied by 121Sb Moessbauer spectroscopy. The near consistency in the isomer shift (-4.3 to -4.6 mm/s relative to InSb) implies almost no change in the s-character in the total Sb-ligand bonds. Variation in the values of the quadrupole coupling const. and the asymmetry factor are discussed in terms of structure and/or changes in the p-character of the Sb-ligand bonds. .
