New Coordination Polymers of Selected Lanthanides with 1,2-Phenylenediacetate Linker: Structures, Thermal and Luminescence Properties.

Solvothermal reactions of lanthanide (III) salts with 1,2-phenylenediacetic acid in ,'-dimethylformamide (DMF) solvent lead to the formation of the metal complexes of the general formula Ln(1,2-pda)(DMF), where Ln(III) = Pr(), Sm(), Eu(), Tb(), Dy(), and Er(), 1,2-pda = [CH(CHCOO)]. The compounds were characterized by elemental analysis, powder and single-crystal X-ray diffraction methods, thermal analysis methods (TG-DSC and TG-FTIR), infrared and luminescence spectroscopy. They exhibit structural similarity in the two groups (Pr, Sm, and Eu; Tb, Dy, and Er), which was reflected in their thermal behaviours and spectroscopic properties.

Two Related Copper(I) π-Complexes Based on 2-Allyl-5-(2-pyridyl)-2H-tetrazole Ligand: Synthesis and Structure of [Cu(2-apyt)NO3] and [Cu(2-apyt)(H2O)](BF4) Compounds.

By means of the alternating current electrochemical technique two new π-compounds [Cu(2-apyt)NO3] (1) and [Cu(2-apyt)(H2O)](BF4) (2) have been obtained starting from the mixture of 1-allyl-5-(2-pyridyl)-2H-tetrazole (1-apyt), 2-allyl-5-(2-pyridyl)-2H-tetrazole (2-apyt) and corresponding copper(II) salts, and have been structurally studied. Selective complexation towards 2-allyl- isomer results in a formation of 2-apyt complexes. Copper(I) ion in both 1 and 2 complexes coordinates the allylic C=C bond, one pyridyl and one tetrazole N atoms.

First Silver(I) - Complexes with Tetrazole Allyl Derivatives. Synthesis and Crystal Structure of [Ag2(C10H10N4S)2(H2O)2](BF4)2 and [Ag(C10H9ClN4S)(NO3)] π-Compounds (C10H10N4S and C10H9ClN4S - 5-(Allylthio)-1-phenyl- and 5-(Allylthio)-1-(4-chlorophenyl)-1H-tetrazole).

Crystalline silver(I) π complexes [Ag2(atpt)2(H2O)2](BF4)2 (1) (atpt - 5-(allylthio)-1-phenyl-1H-tetrazole (C10H10N4S)) and [Ag(atcpt)(NO3)] (2) (atcpt - 5-(allylthio)-1-(4-chlorophenyl)-1H-tetrazole (C10H9ClN4S)) complexes have been obtained using silver salt and the organic ligands. Compounds were characterized by X-ray single crystal diffraction: for 1 space group P21/n, a = 10.4560(5), b = 11.
