}] (3) were formed as a byproduct andidentified by X-ray diffraction (Figure S38 in the SupportingInformation). Compound 2 was crystallized for X-ray dif-fraction (Figure 1, top) by diffusion of diethyl ether into aDMF solution. Prominent intracore distances and angles, aswell as bond lengths and angles to the terminal donor atoms,are in agreement with the corresponding values determinedfor the related homoleptic {N
Ballmann et al. (2008) studied this question.
