摘要
The title complex, [Cd(Pyphen)(1,4-BDC)(H_2O)]·0.5Pyphen (1) (Pyphen=pyrazino[2,3-f][1,10]phenanthr-oline and 1,4-H_2BDC=1,4-benzenedicarboxylic acid) has been obtained by using hydrothermal synthesis and characterized by elemental analysis, IR, fluorescence spectrum and single-crystal X-ray diffraction. It crystallizes in orthorhombic, space group Pbcn with a=2.489 2(5) nm, b=0.967 88(19) nm, c=2.057 0(4) nm, V=4.955 9(17) nm3, Z=8, CdC_29H_18N_6O_4, Mr=642.89, Dc=1.723 g·cm^(-3), F(000)=2 576, μ(Mo Kα)=0.937 mm^(-1), R=0.039 6 and wR=0.102 6. The compound 1 exhibits one-dimensional chain structures, which are further stacked through π-π interactions to form supramolecular layers. Solid-state luminescent spectrum of the complex 1 indicates intense fluorescent emission.

The compound 1 exhibits one-dimensional chain structures, which are further stacked through π-π interactions to form supramolecular layers. Solid-state luminescent spectrum of the complex 1 indicates intense fluorescent emission.
