“…Such reversible magnetic switching may be applicable in sensors where they would be used to make distinctions between gases such as NH 3 and H 2 O. temperature (HT) is attached to the supplementary materials. The temperature dependence of the molar magnetic susceptibility of 2 was reproduced using an alternating chain model [18], rather than the spin ladder model, with the following magnetic exchange interactions: J1/kB = −7.26 K, J2/kB = −4.42 K, and J3/kB = 0 K. Furthermore, 2 exhibited an antiferromagnetic transition at 3.4 K [19].…”

We report reversible structural transformation that occurs in two ladder compounds: Cu2CO3(ClO4)2(NH3)6 (1) and Cu2CO3(ClO4)2(NH3)5(H2O) (2), when they are exposed to gaseous vapors. The ladder structures of both 1 and 2 consist of two Cu2+ ions and one CO32− ion. In 1, the Cu2+ ions are coordinated by three NH3 molecules on each side, while those in 2 are coordinated by three NH3 molecules on one side, and two NH3 molecules and one H2O molecule on the other side. We demonstrated reversible transformation of 1 and 2 via the exposure of 1 to H2O vapor and the exposure of 2 to NH3 vapor using a simple bench-scale method. The minor structural change observed led to a significant difference in physical properties, which we observed using several methods.
