Abstract The isomeric complexes [Fe (1-bpp) 2] 2+ and [Fe (3-bpp) 2] 2+(1-bpp= 2, 6-di
[pyrazol-1-yl] pyridine; 3-bpp= 2, 6-di [1H-pyrazol-3-yl] pyridine) and their derivatives are …

The relationship between chemical structure and spin state in a transition metal complex has
an important bearing on mechanistic bioinorganic chemistry, catalysis by base metals, and …

Two acyclic tetradentate Schiff base ligands, HLX–OH (X= H and Br), were synthesised by 2:
1 condensation of either 2-pyridinecarboxaldehyde or 5-bromo-2-pyridinecarboxaldehyde …

A catalytic domino spirocyclization of 1, 7-enynes with simple cycloalkanes and cyclo-1, 3-
dicarbonyls has been established via multiple C–C bond formations from alkynyl/alkenyl …

Spin-transition compounds are one of the most versatile types of molecular switch. 1–3 They
undergo an electronic rearrangement under a physical stimulus from a high-spin state, with …

A new phenyl-triazole-pyrazine ligand, 4-p-tolyl-3-(phenyl)-5-(2-pyrazinyl)-1, 2, 4-triazole
(tolpzph), was prepared in order to enforce pyrazine coordination of the iron (II) centre in the …

A key step in cytochrome P450 catalysis includes the spin‐state crossing from low spin to
high spin upon substrate binding and subsequent reduction of the heme. Clearly, a weak …

We exploited the solvatochromic spin-state switching in a spin crossover (SCO) compound
based on the FeII complex and the simultaneous change of spectroscopic properties for …

Oxo-and hydroxo-bridged diiron active centers are common structural motifs found in a
variety of proteins in biology. The highly versatile oxo/hydroxo-bridged dimetallic centers …

A mononuclear iron (II) neutral complex (1) was screened for colorimetric sensing abilities
for a wide spectrum of vapor-phase analytes including toxic gases. Although 1 possesses a …
