Syntheses,crystal structures and photoluminescence of the series of 8-hydroxyquinoline metal complexes

Transition complexes of [Al(C9H8NO)3](1),[Co(C9H8NO)3](2),and [Cu(C9H8NO)2](3) have been synthesized.The single-crystal structures of the complexes were all determined by X-ray diffraction.Three crystals belong to monoclinic system with space group of P2(1)/n.The cell parameters are a=1.122 7(8)nm,b=1.301 7(9)nm,c=1.681 2(9)nm,β=95.064(9)°,V =2.447(3)nm3,Z =4,F(000)=1 024 for complex(1),a=1.124 0(12)nm,b=1.289 4(14)nm,c=1.666 5(18)nm,β=95.068(10)°,V =2.406(4)nm3,Z =4,and F(000) =1 048 for complex(2),a=1.065 7(14)nm,b=0.861 1(11)nm,c=1.525 1(2)nm,β=102.229(2)°,V =1.367 7(3)nm3,Z =4,F(000)=716 for complex(3).At the same time,the UV-VIS-NIR,IR and fluorescence spectra of the complexes were measured and analyzed.
