Solvent-modulated reversible conversion of a [2×2]-grid into a pincer-like complex
文献信息

The triazine derived ligand 1 reacts with one equivalent of Co(II) salts to give complexes whose architecture depends on the solvent employed: the [2×2]-grid like tetranuclear complex and the pincer-like mononuclear complex, obtained respectively by crystallization from nitromethane and from acetonitrile may be interconverted reversibly, the grid-pincer conversion being markedly accelerated by adding an amine.
