32. c, it gradually reverted to the purple-colored low-spin state. Although (G0trz)Fe behaved similarly, a longer immersion under wet conditions was necessary for the spin transition to the low-spin state.

35. The thermogravimetric analysis (TGA) of the complexes showed no substantial weight loss upon heating to at least 150°C. Therefore, these complexes are robust in the temperature range for spin transition below 100°C.

37. 5 have reported that a hexagonal phase formed from a core-shell rod with a high electron density in the core hardly shows (11) and (20) reflections in XRD. This may be the reason the (11) and (20) reflections are obscure in Figure 6.
