Resumen:
The Zn complexes bis(acetylacetonato-2O,O0)bis{40-[4-(methylsulfanyl)phenyl]-4,20:60,400-terpyridine-N1}zinc(II), [Zn(C5H7-O2)2(C22H17N3S)2], (I), and {-40-[4-(methylsulfanyl)phenyl]-4,20:60,400-terpyridine-2N1:N10 0}bis[bis(acetylacetonato-2O,O0)-zinc(II)], [Zn2(C5H7O2)4(C22H17N3S)], (II), are discrete entitieswith different nuclearities. Compound (I) consists of twocentrosymmetrically related monodentate 40-[4-(methylsulfanyl)phenyl]-4,20:60,400-terpyridine (L1) ligands binding toone ZnII atom sitting on an inversion centre and twocentrosymmetrically related chelating acetylacetonate (acac)groups which bind via carbonyl O-atom donors, giving anN2O4 octahedral environment for ZnII. Compound (II),however, consists of a bis-monodentate L1 ligand bridgingtwo ZnII atoms from two different Zn(acac)2 fragments. Intraandintermolecular interactions are weak, mainly of the C?H and ? types, mediating similar layered structures. Incontrast to related structures in the literature, sulfur-mediatednonbonding interactions in (II) do not seem to have anysignificant influence on the supramolecular structure.
