“…deviation of 0.120 Å. The Bi-O distance of 2.464 (10) Å is slightly longer compared to the reported value of of 2.424 (10) Å (Kyriakidis et al, 1990). The Bi-Cl distances (Table 1) lie in the range 2.535 (3) Å-2.928 (4) Å, with the Bi-C1 distances involving the bridging C1 atoms being longer (2.859 (4) Å-2.928 (4) Å).…”

The title compound, (C4H7N4O)2[Bi2Cl9(C4H7N4O)]·H2O, was prepared by the reaction of bismuth trichloride and 5-amino-1H-imidazole-4-carboxamide in a dilute HCl medium. The asymmetric unit contains two 5-amino-4-aminocarbonyl-1H-imidazol-3-ium cations, one edge-shared non-centrosymmetric bioctahedral [Bi2C19(C4H7N4O)]2− dianion and a water molecule. In the dianion, the planar 5-amino-4-aminocarbonyl-1H-imidazol-3-ium ligand occupies an equatorial site and is inclined at an angle of 75.7 (2)° to the Bi2(μ-C1)2 plane. The salt forms a three-dimensional network arising from hydrogen bonds between cations, anions and water molecules.

“…Hydrazone derivatives have been used to develop various functional molecules in which proton dynamics such as proton relay are observed. − In addition, Fe(II) complexes with NNO-type hydrazone ligand exhibit spin transition. − We designed an Fe(II) complex with a ligand of N ′-(di(pyridin-2-yl)methylene)-benzohydrazide (HL) derivative, where the HL possesses a hydrazone group and a pyridine ring (Figure (a)). The HL can form an intramolecular hydrogen bond between the N site in the pyridine ring (Py-N) and the N site in the hydrazone moiety (Hyd-N) even while forming a metal complex (Figure (a)). − The Py-N and Hyd-N–H in hydrazone can act as proton acceptor and proton donor sites, respectively. Furthermore, the ligand field of HL on an Fe(II) ion is within the spin-transition region.…”

Observation of Proton Transfer Coupled Spin Transition and Trapping of Photoinduced Metastable Proton Transfer State in an Fe(II) Complex

An important technique to realize novel electron-and/or proton-based functionalities is to use a proton−electron coupling mechanism. When either a proton or electron is excited, the other one is modulated, producing synergistic functions. However, although compounds with proton-coupled electron transfer have been synthesized, crystalline molecular compounds that exhibit proton-transfercoupled spin-transition (PCST) behavior have not been reported. Here, we report the first example of a PCST Fe(II) complex, wherein the proton lies on the N of hydrazone and pyridine moieties in the ligand at high-spin and low-spin Fe(II), respectively. When the Fe(II) complex is irradiated with light, intramolecular proton transfer occurs from pyridine to hydrazone in conjunction with the photoinduced spin transition via the PCST mechanism. Because the light-induced excited high-spin state is trapped at low temperatures in the Fe(II) complexa phenomenon known as the light-induced excited-spinstate trapping effectthe light-induced proton-transfer state, wherein the proton lies on the N of hydrazone, is also trapped as a metastable state. The proton transfer was accomplished within 50 ps at 190 K. The bistable nature of the proton position, where the position can be switched by light irradiation, is useful for modulating proton-based functionalities in molecular devices.

The crystal structure of the title compound, (CI 8 HI 2 C1N 4 0 2 ) 2 U, has been determined from three-dimensional X-ray diffraction data. The structure is monoclinic, space group P2,/c, with a = 7.545(1), b = 19.890(1), c = 12.210(1) Α, β = 110.66(1)°, V= 1714.52 A 3 and Ζ = 2. The structure was solved by direct methods and refined by least-squares to a final R = 0.025 (R w = 0.027, R g = 0.036). The uranium atom lies on a crystallographic symmetry center, while the tridentate organic ligand binds equatorially to the uranyl ion, U0 2 + , leading to eight-coordinated uranium in a distorted hexagonal bipyramidal coordination geometry. Selected bond lengths: U-O(uranyl) 1.764(5) Ä, U-O(ligand) 2.364(4) Ä, U-N 2.634(5)-2.702(5) A. The crystal cohesion is due to normal van der Waals forces. The IR and UV spectra are in accordance with the established geometrical features of the structure.Brought to you by |
