Mössbauer Spectroscopic Studies of Monosubstituted Pentacyano Ferrate ( II ) Complexes ,

Mössbauer Spectra, Hexacoordinate Complexes A series of compounds Na3[Fe(CN)5RNH2] * nH 20 where R = -H, -CH3, -C2H5, n-C3H7, n-C4H9 and -CH2C6H5 and RNH2 = C5H5N have been studied by Mössbauer spectroscopy. Quadrupole splitting (A EQ) values vary in a limited range (0.68-0.80 mm/sec) indicating only small distortions in the octahedral geometry of the compounds with the substitution of various ...

Pressure effects and Mössbauer spectroscopic studies on a 3D mixed-valence iron spin-crossover complex with NiAs topology.

A three-dimensional mixed-valence iron complex with NiAs-type topology, [(Fe(III)(3)O)Fe(II)(TA)(6)(H(2)O)(3)].(ClO(4))(2)(NO(3))(EtOH)(H(2)O)(2) (1, HTA = tetrazole-1H-acetic acid), shows spin-crossover behavior that was characterized via variable-temperature crystal structures, Mössbauer spectra and magnetic susceptibilities, the pressure effects on the transition behavior were also studied.

Structure:function relationships in molecular spin-crossover complexes.

Spin-crossover compounds are becoming increasingly popular for device and sensor applications, and in soft materials, that make use of their switchable colour, paramagnetism and conductivity. The de novo design of new solid spin-crossover compounds with pre-defined switching properties is desirable for application purposes. This challenging problem of crystal engineering requires an understandi...

Magnetic fluorescent bifunctional spin-crossover complexes.

The rational design of magnetic and fluorescent bifunctional materials is attracting increasing interest. In this study, two mononuclear Fe(ii) complexes, namely [Fe(L)2(NCS)2] (1) and [Fe(L)2(NCSe)2] (2) are synthesised by combining a spin-crossover unit and a fluorescent ligand (naphth-1-yl)-N-(3,5-di(pyridin-2-yl)-4H-1,2,4-triazol-4-yl)methanimine (L) to achieve bifunctionality. Single-cryst...

Spin-crossover in cobalt(II) imine complexes

Whereas there are hundreds of known iron(II) spin-crossover compounds, only a handful of cobalt(II) spin-crossover compounds have been discovered to date, and hardly an in depth study on any of them exists. This review begins with an introduction into the theoretical aspects to be considered when discussing spin-crossover compounds in general and cobalt(II) systems in particular. It is followed...
