The novel boryl anions NHC–B(CN) ₂ ⁻ complete a series of cyanoborates with continuously increasing boron-centred nucleophilicity.

Fe ²⁺ spin crossover complexes [Fe( L ) ₂ ] ²⁺ (L = substituted (pyridin-2-yl)-1,10-phenanthroline) were prepared and SCO properties were investigated in solution and in the solid state by an experiment and in silico .

Fe ²⁺ spincrossover complexes [Fe( L ) ₂ ] ²⁺ (L = substituted (pyridin-2-yl)-1,10-phenanthroline) were prepared and SCO with changing coordination numbers was identified by ¹ H NMR spectroscopy and in silico modeling.
