Spin-Crossover Behavior of Hofmann-Type-Like Complex Fe(4,4’-bipyridine)Ni(CN)4nH2O Depending on Guest Species

A newly prepared metal complex Fe(4,4’-bipyridine)Ni(CN)4 ̈ nH2O, which was estimated to have a structure similar to the Hofmann-type clathrate host, changed its color from orange to deep orange and yellow on exposure to ethanol and acetone vapor, respectively, and the respective samples showed thermally induced two-step and one-step spin transitions.

IR Spectroscopic Study of M ( Benzoic Acid ) 2 Ni ( CN ) 4 · ( 1 , 4 - Dioxane ) Clathrate ( M = Ni , Cd and Co )

In various studies, Hofmann-type clathrates, given by the general formula ML2Ni(CN)4·G, were produced. Here M is a transition metal atom, L a ligand molecule or half of a bidentate ligand molecule, and G a guest molecule [1]. The clathrates are of interest because of their inclusion behavior and use as catalysts, anti-oxidants and stabilizing agents [2]. Infrared spectroscopy is one of the best...

Synthesis, Spectroscopy and Magnetic Characterization of Five Dinuclear Copper(II) Complexes with 2, 3 or 4-Pyridinemethanol as the Ligand

The synthesis, spectroscopy and magnetic characterization of five new dinuclear copper(II) complexes are described. All five compounds have the general formula [Cu2(L)4(O-R)2](Cl)2 or [Cu2(L)2(Cl)2](Cl)2, in which R = CH3 or H, L=2, 3 or 4-pyridinemethanol as L2, L3 or L4, respectively. The title compounds consist of dinuclear units with bridging methoxo groups in [Cu2(L4)4(O-CH3)2](Cl)2, hydro...
