| 摘 要： | Two new cobalt(Ⅱ)complexesCo_2(2,2?-bipy)_2(dpa)_2(H_2O)_5]·4H_2O(1)and Co(2,2?-bipy)_3(SO_4)]·7.5H_2O(2)have been synthesized with diaphonic acid(H_2dpa)and 2,2?-bipyridine(2,2?-bipy)as ligands.In 1,two neighboring cobalt(Ⅱ)ions are linked together by one bridging diaphonic acid group,forming an asymmetric dinuclear structure.1 crystallizes in triclinic,space group ■ with a=9.825(6),b=13.007(8),c=19.586(1)?,α=80.773(1)o,β=77.065(1)o,γ=85.902(1)o,M_r=431.4,V=2406.5(3)?~3,D_c=1.48 g/cm~3,Z=2,μ(Mo Kα)=0.767 mm~(-1),F(000)=1112,the final R=0.0379 and wR=0.0862.The central cobalt(Ⅱ)ions in 1 and 2 are coordinated with six atoms,forming distorted octahedral coordination geometry.The fluorescence and thermal stability properties of 1 and 2 are also reported.
