【摘要】:The interaction of metal ions(Hg~(2+),Pb~(2+),Co~(2+),Mn~(2+)) with polypyridyl quinoxaline ligand 2,3,6,7,10,ll-hexakis(2-pyridyl)dipyrazino[2,3-f:20,30-h]quinoxaline(HPDQ) was investigated,and four new complexes have been synthesized and characterized.Complex 1 exhibits a 0dimensional dual-core structure,2 is a one-dimensional chain structure based on a dual-core Pb unit,while 3 and 4 show a 0 dimensional single-core structural unit.Complex 1 is of monoclinic system,space group C2/c with a = 19.211(4),b = 23.896(5),c = 12.698(3) ?,β= 120.11(3)°,V= 5043.0(17)?~3,Z = 4,S = 1.053,F(000) = 2976,R~a = 0.0637 and wR~b = 0.1068(I 2σ(I)).Complex 2 adopts triclinic system,space group P1 with a = 10.370(2),b = 12.195(2),c = 21.033(4) ?,α = 80.87(3),β= 81.22(3),γ = 82.38(3)°,V= 2579.3(8) ?~3,Z = 2,S = 1.099,F(000) = 1328,R~a = 0.0609 and wR~b =0.1365(I 2σ(I)).Complex 3 is of monoclinic system,space group Cllc with a = 14.166(3),b =16.621(3),c = 20.248(4) ?,β = 92.18(3)°,V= 4764.0(16) ?~3,Z = 4,S = 1.005,F(000) = 2108,R~a =0.0589 and wR~b = 0.1332(I 2σ(I)).Complex 4 belongs to the monoclinic system,space group C2/c with a = 14.404(3),b = 16.626(3),c = 20.346(4) ?,β = 92.43(3)°,V= 4868.2(17) ?~3,Z = 4,S= 1.068,F(000) = 2108,R~a = 0.0833 and wR~b = 0.1591(I 2σ(I)).Furthermore,the behavior of HPDQ with Hg~(2+),Pb~(2+),Co~(2+) and Mn~(2+) in the solution was also investigated,and the result shows after the metal ions were added respectively,the emission of all solutions shows fluorescence quenching and has a red shift compared with that of the HPDQ ligand.
