“…X-Ray Powder Patterns. As Inoue et al 8 have previously shown, the Fe2+, Co2+, Ni2+, and Zn2+ salts of nitroprusside adopt the face-centered cubic lattice characteristic of Prussian Blue and its analogs, and our X-ray data are in accord with these results. The reported8 lattice parameters are as follows: Fe2+, 10.35 A; Co2+, 10.28 A; Ni2+, 10.22 A; Zn2+, 10.36 A.…”

“…The broad band between 490 and 700 nm can be assigned to the d-d transition of nickel. 33 This d-d absorption appears in almost the same wavelength region as that of the aquo complex of nickel. The absorption band existing between 340 and 490 nm as a shoulder can be assigned to the transitions 1…”

“…for nitroprusside, in which the 2b 2 f7e MLCT transition is believed to appear in the range 441-481 nm. 33,34 Thus, it can be reasonably expected that irradiation in the 441-481 nm range can induce a MLCT from Fe to NO in the nitroprusside unit. In the case of sodium nitroprusside, potassium nitroprusside, and barium nitroprusside, for example, this MLCT yields a new electronic configuration state which can persist for long time at low temperature.…”

A new approach for designing optically switchable molecular communication devices based on spin-exchange interactions is proposed in the present paper. The device is constituted from two parts, i.e., a paramagnetic block (PMB) and a coupling control block (CCB). As a prototype of this model, nickel nitroprusside, Ni[Fe(CN)5NO]·5.3H2O was synthesized, in which the nickel ion acts as the PMB and the nitroprusside molecule does as the CCB. In this compound, as there is no spin on Fe, the magnetic interaction between the neighboring Ni cations is very weak. No magnetic phase transition can be observed until 1.8 K. Photoirradiation at 475 nm causes a charge transfer from the metal, Fe, to the ligand, NO, which induces two antiferromagnetically coupled spins on Fe and NO. Furthermore, the new spin on Fe interacts ferromagnetically with those on neighboring nickels. As a result, the spins on the Ni ions, which surround the Fe with spin, form a magnetic cluster with S = 5.

“…Surprisingly, Prussian blue analogues of the type M[Fe(CN)5NO] xH20 (M = Mn, Fe, Co, Ni, Cu and Zn) have been investigated by a variety of spec troscopic methods, e.g. electronic absorption [4], in frared absorption [5,6], Mössbauer [7,8] and X-ray photoelectron spectroscopy [9]. However, the ther mal decomposition of M[Fe(CN)5N 0 ] jcH20 has received less attention, although a few Prussian blue analogues have been extensively studied [10].…”

The structure and properties o f the thermal decomposition products of Fe[Fe(CN)sNO] • x H2O (x = 5~6 ) have been studied by M össbauer and FT-IR spectroscopy, X-ray diffraction, and conductivity measurements. The valence state and coordination environment of the iron ions change dramatically when the nitrosyl ligand is eliminated by heat-treatment under vacuum at 200 °C. The dark blue product obtained by heat-treatment under vacuum at 250 °C is characteristic of the mixed-valence state in Prussian blue analogues. The electrical conductivity of the dark blue product is higher by a factor o f 103 than that o f the starting material because of the mixed-valence state between Fe(III)[Fe(II)(CN)5] and Fe(II)[Fe(III)(CN)5]. Heat-treatment under vacuum at 350°C yields a new product Fe(II)[Fe(II)(CN)4] the crystal structure of which is different from that of the starting material. The electrical conductivity of the decomposition product obtained at 350 °C is about 105 times higher than that of the starting material.
