Abstract
In recent decades the mechanosynthesis of Coordination Polymers (CPs) has consolidated as a powerful method for the formation of coordination bonds. The aim of this study regards the environmental friendly mechanosynthesis of coordination polymers by milling the neutral square planar NiIIcomplexes [((MeO)2PS2)2Ni] (1), [((EtO)2PS2)2Ni] (2), [((MeO–C6H4)(MeO))PS2)2Ni] (3), [((MeO–C6H4)(EtO))PS2)2Ni] (4), with the organic ligand 1,4-di(3-pyridyl)buta-1,3-diyne (L). Using these substrates, several mechanosynthesis were performed via Net Grinding (NG) and Liquid Assisted Grinding (LAG) approaches. A mechanochemical trend concerning the general inverse correlation between melting point of reagents and reactivity has been observed, highlighting a possible mechanism for these reactions under mechanical conditions.File | Size | Format | |
