Abstract
Abstract Reaction of 4′-chloro-2,2′:6′,2″-terpyridine with 3-phenyl-n-propanol or n-propanol in the presence of excess KOH in dmso, respectively, yields 4′-(3-phenylpropoxy)-2,2′:6′,2″-terpyridine (L2) and 4′-(3-propoxy)-2,2′:6′,2″-terpyridine (L3). The following complexes of these two ligands have been prepared: [{Cu(μ-Cl)L}2](BF4)2, [Cu(NCMe)(L)](BF4)2, [PdCl(L)]BF4 and [PtCl(L)]BF4 (L=L2, L3). Recrystallisation of [Cu(NCMe)(L2)](BF4)2 from PhCN/Et2O yields [Cu(NCPh)(L2)](BF4)2, whose crystal structure shows a square planar Cu(II) ion with substantial disorder in the PhCN ligand and 3-phenylpropoxy tail. The single crystal structure of [PdCl(L2)]BF4·2CH3NO2 contains a square planar Pd(II) centre. Neither of these structures, nor the solution spectroscopic or electrochemical data from the complexes, provide any evidence for intramolecular π–π interactions between the terpyridine ring and phenylpropoxy substituent. (Non-SI unit employed: 1 G=10−4 T.)
