    • Kα, graphite monochromated, λ = 0.71073 Å). These structures were solved by using direct methods. After refinement of the non-hydrogen atoms, difference Fourier maps revealed maxima of residual electron density close to positions expected for hydrogen atoms. Hydrogen atoms were introduced as fixed contributors at calculated positions (C-H = 0.95 Å, B(H) = 1.3 Beqv(C)). All calculations were made by using the Nonius OpenMoleN package. [19] Neutral atom-scattering-factor coefficients and anomalous dispersion coefficients were taken from a standard source.
