Abstract

The reactivity of the iminodiphosphane C6H4(o-CN)N= PPh2-PPh2, which contains an N=P-P unit, has been investigated. Reaction with small molecules, [viz. H2O/O-2, H2O2, CH3OH, C6H4(o-CN)NH2] and elemental sulfur result in cleavage of the P-P bond to give aminophosphane-derivatised compounds. The products from these reactions have been characterized spectroscopically, including two by single-crystal X-ray diffraction. The reactivity of the iminodiphosphane towards the transition metal complexes [M(cod)Cl-2] (M = Pd or Pt) has also been investigated. In the reactions, the immodiphosphane rearranges to form the more common diphosphonylamine (P-N-P) unit which chelates to the metal centres, Three different compounds were isolated from these reactions and they have all been fully characterised by spectroscopy and single-crystal X-ray diffraction.

X-ray crystallography

X-ray crystallography is the experimental science determining the atomic and molecular structure of a crystal, in which the crystalline structure causes a beam of incident X-rays to diffract into many specific directions. By measuring the angles and intensities of these diffracted beams, a crystallographer can produce a three-dimensional picture of the density of electrons within the crystal. From this electron density, the mean positions of the atoms in the crystal can be determined, as well as their chemical bonds, their crystallographic disorder, and various other information.

Powder diffraction

Powder diffraction is a scientific technique using X-ray, neutron, or electron diffraction on powder or microcrystalline samples for structural characterization of materials. An instrument dedicated to performing such powder measurements is called a powder diffractometer. Powder diffraction stands in contrast to single crystal diffraction techniques, which work best with a single, well-ordered crystal. Diffraction grating The most common type of powder diffraction is with x-rays, the focus of this article although some aspects of neutron powder diffraction are mentioned.

X-ray scattering techniques

X-ray scattering techniques are a family of non-destructive analytical techniques which reveal information about the crystal structure, chemical composition, and physical properties of materials and thin films. These techniques are based on observing the scattered intensity of an X-ray beam hitting a sample as a function of incident and scattered angle, polarization, and wavelength or energy.
