Structural investigations of phosphorus–nitrogen compounds. 2. The structures of N3P3(NH2)2Cl4, N3P3(NPPh3)(NH2)Cl4 and N3P3(NPPh3)Cl5 and a comparison with other phosphazenylphosphazenes. The relationship of conformation in the solid state to conformation in solution

Abstract

Discussion sur la conformation a l'etat solide determinee a partir des angles diedus des substituants phosphazenyl par rapport au cycle et sur les conformations preferentielles en solution mesurees a partir des constantes de couplage spin-spin 4 J(PP)
