The cobalt(II) complex with a n-butyl group in its ligand, [Co(NO 3) 2 (L)] (complex 1), was synthesized by layering an acetone solution of a planar tridentate N-containing ligand (L=n-butyl-2,6 ...

Two different colored cobalt(II) complexes exist in equilibrium, [Co(H 2 O) 6] 2+ (pink) and [CoCl 4] 2- (blue). This equilibrium may be disturbed by changing temperature - when placed in a cold bath, ...
