The Interaction of Nickel(II) and Copper(II) Schiff Base Complexes with Diorganotin(IV) Dichlorides in Acetonitrile: A Thermodynamic Study

摘要

Adduct formation of nickel(II) and copper(II) Schiff base complexes, (NiL) and (CuL), as donors with diorganotin(IV) dichlorides as acceptors has been investigated spectrophotometrically, in acetonitrile. L is ?±,?±a?2-Me₂-salen, N,N a?2-ethylenebis(?±-methylsalicylideneiminate) (1), ?±,?±a?2-Me₂-salpn, N,N a?2-1,2-propylenebis(?±-methylsalicylideneiminate) (2), ?±,?±a?2-Ph₂-salen, N,N a?2-ethylenebis(?±-phenylsalicylideneiminate) (3), and ?±,?±a?2-Ph₂-salpn, N,N a?2-1,2-propylenebis(?±-phenylsalicylidene- iminate) (4). The trend of adduct formation of the nickel(II) and copper(II) Schiff base complexes with a given tin compound decreases as follows: M(?±,?±a?2-Me₂-salen) > M(?±,?±a?2-Me₂-salpn) > M(?±,?±a?2-Ph₂-salen) > M(?±,?±a?2-Ph₂-salpn). The trend of the reaction of R₂SnCl₂ toward a given nickel(II) or copper(II) Schiff base complex is Ph > Me > Bu. The trend of the metal reactivity in a given Schiff base toward a given diorganotin(IV)dichloride at the same temperature is Cu(II) > Ni(II).View full textDownload full textKeywordscopper(II) complexes, diorganotin(IV) dichlorides, nickel(II) complexes, Schiff base, thermodynamicRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/15533174.2011.591362
