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 …

This article surveys the relationship between ligand type, coordination geometry and metal
spin state in complexes of iron and other metal ions. Compounds and materials containing …

Spin‐crossover between high‐spin (HS) and low‐spin (LS) states of selected transition
metal ions in polynuclear and polymeric compounds is behind their use as multistep …

Many paramagnetic metal complexes have emerged as unique magnetic materials (single-
molecule magnets), which behave as conventional magnets at the single-molecule level …

Guided by DFT based modeling the chemical shift range of a hydride resonance in the
proton nuclear magnetic resonance (NMR) spectrum of the intermediate-spin, square planar …

A new synthetic pathway is devised to selectively produce previously elusive heteroleptic
iron (II) complexes of terpyridine and N, N′-disubstituted bis (pyrazol-3-yl) pyridines that …

The large paramagnetic shifts and short relaxation times resulting from the presence of a
paramagnetic centre complicate NMR data acquisition and interpretation in solution. As a …

Here we report the first successful attempt to identify spin-crossover compounds in solutions
of metal complexes produced by mixing different ligands and an appropriate metal salt by …

The molecular design of spin‐crossover complexes relies on controlling the spin state of a
transition metal ion by proper chemical modifications of the ligands. Herein, the first N, N' …

Here, we report a combined study of the effects of two chemical modifications to an N, N′-
disubstituted bis (pyrazol-3-yl) pyridine (3-bpp) and of different solvents on the spin …
