  摘要：

  AbstractThree new complexes {[Cu(L1)2(NO3)2]⋅H2O}oo (1), {[Cu4(L2)2(OAc)8]‐CH3CH2OH}oo (2) and [Cd2(L3)3(NO3)4(H2O)2]oo (3) (L1=4‐phenyl‐7‐(pyridine‐3‐yl)‐1,2,4‐triazolo[3,4‐b]‐1,3,4‐thiadiazole, L2=4‐(pyridine‐3‐yl)‐7‐phenyl‐1,2,4‐triazolo[3,4‐b]‐1,3,4‐thiadiazole, and L3=4‐(pyridine‐4‐yl)‐7‐phenyl‐1,2,4‐triazolo[3,4‐b]‐1,3,4‐thiadiazole) have been synthesized and characterized by elemental analyses, IR spectra and single crystal X‐ray diffraction. The structural analyses reveal that complex 1 is a neutral 2‐D network structure with a 44 topology, 2 has a 1‐D neutral coordination chain with a [Cu2(CH3COO)4] dinuclear structural unit bridged by four acetate ions, and 3 is a neutral rhombohedral grid structure. All thecomplexes are air stable at room temperature. Furthermore, the fluorescent properties of complex 3 and corresponding ligand L3 have been investigated and discussed.

  In efforts to explore the effects of metal ions, ligand structures, counteranions on the structures and properties of metal-organic complexes, seven d(10) metals (Zn and Cd) and transition metals (Cu and Co) coordination compounds with condensed heterocyclic based 1,2,4-triazole 4,7-diphenyl-1,2,4-triazolo[3,4-b]-1,3,4-thiadiazole (L-1), 4-phenyl-7-(pyridine-3-yl)-1,2,4-triazolo[3,4-b]-1,3,4-thiadiazole (L-2), 4-phenyl-7-(pyridine-4-yl)-1.2,4-triazolo[3,4-b]-1,3,4-thiadiazole (L-3), and 4-(pyridine-3-yl)-7-(pyridine-4-yl)-1,2,4-triazolo[3,4-b]-1,3,4-thiadiazole (L-4), Zn(L-1)(2)Cl-2 (1), Co(L-1)(2)Cl-2 (2), [Cd(L-2)(2)(H2O)(2)]center dot (ClO4)(2)}(infinity) (3), Cd(L-2)(2)(NO3)(2)(H2O)(2) (4), [Cu(L-3)(2)(NO3)(2)]center dot(CH2O2)}(infinity) (5), [Cu(L-3)(2)(OH)(MeOH)]center dot(MeOH)(2)center dot BF4}(infinity) (6) and [Cd(L-4)(2)(NO3)2](infinity) (7) were synthesized and structurally characterized by elemental analyses, 1R spectroscopy and single-crystal X-ray diffraction. Complexes 1,2 and 4 have a mononuclear structure, 1 and 2 have similar structure, 3 and 6 have a neutral rhombohedral grid with a (4,4) topology, the coordination network of 3 further assembled into a three-dimensional framework by O-H center dot center dot center dot O hydrogen-bonding interactions, 5 reveals a coordination chain structures consisting of a neutral chain [Cu(L-3)(2)(NO3)(2)]center dot(CH2Cl2)}(infinity) with the Cu-II centers, and 7 has a coordination chain. Obviously, the structural differences among them are attributable to the difference of metal ions, counter-anions, the locality and amount of coordination atoms in ligands framework. All the complexes are air stable at room temperature. Furthermore, the fluorescent properties of complexes 1, 3, 4, 7 and corresponding ligands have been investigated and discussed.
