Spin Crossover in a Vacuum-Deposited Submonolayer of a Molecular Iron(II) Complex
By using a carbon-based substrate, the spin-crossover behavior can be preserved even for molecules that are in direct contact with a solid surface.

Bond Activation in Iron(II) and Nickel(II) Complexes of Polypodal Phosphanes
A pyridine-derived tetraphosphane ligand (donor set: NP₄) has been found to undergo specific C–P bond cleavage, thereby producing a ligand with an NP₃ donorset.

“… and honour their art!” – Evaluation of Historical and New Routes to 1,5-Dihydroxy-6-oxo-1,6- dihydropyridine-2-carboxylic Acid and 1,3-Dihydroxy-2-oxo-3-pyrroline-4-carboxylic Acid
We present a new two-step synthesis of the similarly substituted 5-hydroxy-6-oxo-1,6-dihydropyridine-2-carboxamide using succinyl cyanide.
