Crystal structure of di-p-tolyl mercury

Abstract

Di-p-tolyl mercury crystallizes in space group P21/c with cell constants a = 10.12, b = 5.07, c = 11.65 Å, β = 91.8°, Z = 2. The structure was solved by mercury-phased three-dimensional electron density Fourier synthesis and refined by least-squares. The final R-index was 0.085 for all reflections. The molecule of di-p-tolyl mercury is found to be planar having linear carbon–mercury–carbon bonds. There are no significant intermolecular close approaches, the structure is, therefore, of molecular type.
