Condensation of 3-(aminomethyl)pyridine with acetylacetone in the presence of 2 equiv. of HCl affordedN,Na'-bis(3-pyridylmethyl)-2-amino-4-imino-pent-2- ene, nacnacCH2PyH, a diketimine with pendant pyridine donors.Under the same conditions, 2- and 4-(aminomethyl)pyridine afforded the respective 1-(2-pyridyl)- and 1-(4-pyridyl)-2,4-dimethylpyrrol. The heteroleptic complex (nacnacCH2Py)(nacnacBn)Zn was obtained upon reaction of nacnacCH2PyH with nacnacBnZnEt. Combining 2 equiv. of this ligand with ZnEt2 afforded the homoleptic complex nacnac CH2Py2Zn. The latter forms a 2D coordination polymer upon reaction with [Cu(NCMe)4][PF6], which shows short-lived luminescence at ambient temperature. The coordination polymer and complex (nacnacCH2Py)(nacnacBn)Zn were characterised by single-crystal X-ray diffraction. Zinc complexes of a new bifunctional diketimine ligand with pendant pyridine donor ligands can serve as building blocks for polynuclear or supramolecular assemblies.Reaction of the building block with CuI cations affords a bimetallic, luminescent Cu-Zn coordination polymer.
