    • Diffraction data for 1 were collected at 150 K on a Bruker Smart Apex CCD diffractometer equipped with an Oxford Cryosystems low-temperature device. The structure was solved by direct methods (SHELXS) and refined by full-matrix least squares against F2 (CRYSTALS, CCDC-639301 contains the supplementary crystallographic data for this paper.
