A rhodium dinuclear complex having n-methoxypropyltetramethylcyclopentadienyl (CpMPro = η5-C5Me4nC3H6OCH3) and photoresponsive dithionite (μ-O2SSO2) ligands, [(CpMProRh)2(μ-CH2)2(μ-O2SSO2)] (1MPro), was found to form two polymorphic crystals (a previously reported block-like α-crystal and a newly obtained plate-like β-crystal). The crystalline-state photochromism of 1MPro in the β-crystal, which involves photoisomerization from the μ-O2SSO2 complex (1MPro) to the corresponding μ-O2SOSO complex (2MPro) and a thermal back-reaction from 2MPro to 1MPro, was successfully studied by performing time-dependent X-ray diffraction experiments. The results obtained from the β-crystal were compared with the previous results obtained from the α-crystal: the thermal back-reaction in the β-crystal is eight times longer than that in the α-crystal.
