Unusual motion of the n-methoxypropyl moiety observed in the photochromic crystals of an organorhodium dithionite complex with n-methoxypropyltetramethylcyclopentadienyl ligands

Abstract

Crystalline-state photochromism of a new organorhodium dinuclear complex having n-methoxypropyltetramethylcyclopentadienyl (η-C5Me4n-C3H6OCH3) and photoresponsive dithionite (μ-O2SSO2) ligands was investigated directly by performing single crystal X-ray diffraction experiments; reversible conformational change of...

Crystal polymorphism and crystalline-state photochromism of a rhodium dithionite complex with n-methoxypropyl moieties

“…with Cp R (η 5 -C 5 Me 4 R) and photoresponsive dithionite (μ-O 2 SSO 2 ) ligands are advantageous compounds for investigating and/or understanding the crystalline-state reaction and its induced behaviors. 5 The photochromic reaction involves photoisomerization from the μ-O 2 SSO 2 complex ( 1 R ) to the corresponding μ-O 2 SOSO complex ( 2 R ) and a thermal back-reaction from 2 R to 1 R (Fig. 1a).…”
