ONE DIMENSIONAL X-RAY DIFFRACTION TECHNIQUES AS A ROUTINE STEREO- CHEMICAL TOOL
Abstract
An investigation was made to determine the structures of compounds or groups of compounds from a consideration of functions directly calculable from the x-ray diffraction patterns of powdered samples of the compounds. The study of coordination compounds and complex ions concerned the number and arrangement of ligands about the central coordinated metal ion. The investigation involved the preparation of techniques for showing that a compound or group of compounds had a particular coordination arrangement by considering and comparing the intensity distribution and radial distribution curves obtained experimentally from the compounds and by comparing the curves obtained from observable data with corresponding curves calculated from proposed molecular structures. X-ray powder diffraction photographs were taken of several series of compounds, the members of a series involving slight changes from one compound to another. These series included M dipyridine dihalide where M was a divalent transition metal; a series of cis and trans octahedral compounds; a series of eight coordinated compounds M bisdiarsine tetrachloride where M is Ti, V, Zr or Hf; and a series of compounds containing the complex ions (MCl6)(3-) or (M2Cl9)(3-) where M is Cr, Mo or W.
