Two d10 metal-organic complexes, [ZnBr2(DICNQ)2] (1) and [AgCN(DICNQ)]2(2), were prepared from ZnBr2 and AgCN with 6,7-dicyanodipyridoquinoxaline (DICNQ) by solvothermal reactions, respectively, and characterized by single-crystal X-ray diffraction analyses, IR spectroscopy, and photoluminescent measurement. Compound 1 crystallizes in monoclinic, space group C2/c with a=8.436(2), b=13.011(3), c=27.565(6),β=97.90(3) , V=2997.0(1)3 , Z=4, Mr=789.73, Dc=1.750 g/cm3 ,μ=3.533 mm-1 , F(000)=1552, S=1.007 and T=293(2) K. The final R=0.0739 and wR=0.1380 for 1561 observed reflections with I > 2σ(I). Compound 2 crystallizes in monoclinic, space group P21/c with a=24.202(6), b=7.1619(17), c=18.339(5),β=111.8380(10) , V=2950.6(1)3 , Z=4, Mr=832.32, Dc=1.874 g/cm 3 ,μ=1.382 mm-1 , F(000)=1632, S=1.002 and T=293(2) K. The final R=0.0389 and wR=0.1257 for 4812 observed reflections with I > 2σ(I). Both compounds form packing structures by π…π stacking interactions and C-H…N or C-H…Br hydrogen-bonding interactions. Compounds 1 and 2 show similar photoluminescent spectra with emission maxima at ca. 430 nm in diluted acetonitrile solution (1×10-5 mol L-1 ) at room temperature.
