X-ray Diffraction Study of the Electron Density Distribution in Cyanuric Acid


FOR some time1 X-ray crystallographers have been seeking information about the electron density distribution in chemical bonds. This communication reports some results recently obtained for cyanuric acid at 100° K. Experimental details are listed in Table 1; crystal axes and space-group are as in previous work2,3.
