Two new zinc-containing complexes [Zn2(TEA)(C6H5COO)3] (1) and ([Zn(TEA)(H2O)2]SO4)·H2O (2) were synthesized and characterized by IR spectroscopy, elemental analysis, DSC and TG analysis. Their structure was determined by single-crystal X-ray diffraction. In the binuclear, mixed-ligand [Zn2(TEA)(C6H5COO)3] complex, one zinc atom is six-coordinated by nitrogen and three oxygen atoms of tetradentate triethanolamine (TEA) and two oxygen atoms of two different benzoate ligands, forming the distorted octahedron of the ZnNO5 type. The second zinc atom is five-coordinated, forming the distorted trigonal bipyramid. Two zinc atoms are bridged by two carboxylate groups of two benzoate ligands and one oxygen atom of the deprotonated hydroxyethyl group of TEA. Cationic complex 2 consists of [Zn(TEA)(H2O)2]2+ cations and SO42? anions. The coordination polyhedron around the zinc atom corresponds to a distorted octahedron (ZnNO5 type). The TEA ligand is tetradentately coordinated to the cation, forming three chelate rings. The coordination sphere of the Zn cation is completed by two aqua ligands.

The synthesis of six novel zinc (II) mono(N-heterocyclic carbene) complexes is described. 1,3-Bis(mesityl)-imidazol-2-ylidene was reacted with the zinc salts ZnX2 (X=Cl, CH3COO, PhCOO, and PhCH2COO) to yield the corresponding monomeric Zn-NHC complex ZnCl2(NHC)(THF) (1) and dimeric [Zn(OOCCH3)2(NHC)]2 (2), [Zn(OOCPh)2(NHC)]2 (3), [Zn(OOCCH2Ph)2(NHC)]2 (4) (NHC=1,3-bis(mesityl)-imidazol-2-ylidene). Reaction of 1 with 2 equivalents of silver trifluoromethanesulfonate yielded monomeric Zn(O3SCF3)2(NHC)(THF) (5), reaction of 1 with sodium {[R(+)-α-2-(1-phenyl-ethylimino)-methyl]- phenolate} yielded monomeric ZnCl(OC6H4- 2-CH=N(CHPhCH3)(NHC) (6). Compounds 1, 4-6 were structurally characterized by X-ray analysis. Selected compounds were investigated for their activity in the copolymerization of carbon dioxide with cyclohexene oxide as well as in the ring-opening polymerization of cyclohexene oxide and E-caprolactone.

Reactions between 4′-phenyl-terpyridine (L) and several Zn(ii) salts (trifluoromethane sulfonate, p-toluenesulfonate, benzoate, p-hydroxybenzoate, o-hydroxybenzoate or m-hydroxybenzoate) led to the formation of the complexes [Zn(OSO2CF3)2L(H2O)] (1), [Zn(p-OSO2PhCH3)2L] (2), [Zn(OCOPh) 2L] (3), [Zn(p-OCOPhOH)2L] (4), [Zn(o-OCOPhOH) 2L] (5) and [Zn(m-OCOPhOH)2L] (6), which were characterized by elemental analysis, 1H NMR, 13C NMR, IR, single crystal X-ray diffraction and fluorescence spectroscopies. In 1, the Zn atom is hexacoordinated, with a N3O3 coordination environment, whereas in the remaining structures the metal atom is envisaged as possessing distorted N3O2 irregular trigonal bipyramidal coordination geometries. All the compounds show interesting photo-luminescent properties in solid and solution states in DMF, DMSO and methanol, which are reported along with their TG-DTA thermal decomposition processes.
