摘要：
(Graph Presented) A CN weakling? The cyanide ligand in the five-coordinate iron(II) porphyrinate complex [Fe(tpp) (CN)]- (tpp= tetraphenylporphinato) is not a sufficiently strong-field ligand to cause the complex to be in the low-spin state under all conditions. Rather, the complex displays a reversible low-spin (LS) to high-spin (HS) crossover with no hysteresis. © 2008 Wiley-VCH Verlag GmbH & Co. KGaA.
