All non-hydrogen atoms were refined with anisotropic displacement parameters. The hydrogen atoms of the THF ligands were placed geometrically and they were allowed to ride on the pivot atom with their isotropic displacement parameters fixed at 120% of those of the C atoms they were attached to.

22. 3] (2a) (0.60 g, 0.40 mmol) and 1-hexadecylamine (7.00 g, 29.00 mmol) was purged with argon and heated to 330 °C for 1.5 h and to reflux for another 30 min. The black-brown mixture was cooled to room temperature by removing the heat source and dissolved in benzene (75 ml) under ambient conditions. Next day, the centrifugation (6000 rpm, 10 min) was applied to remove undispersed residue and ethyl alcohol (75 ml) was added. After 1 day, the dark-brown oil was formed and redispersed into hexane (3a).
