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 α = 8.436(2), b = 13.011(3), c = 27.565(6) Å, β = 97.90(3)°, V = 2997.0(1) Å3, 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 α= 24.202(6), b = 7.1619(17), c = 18.339(5) Å, β = 111.8380(10)°, V = 2950.6(1) Å3, Z = 4, Mr = 832.32, Dc = 1.874 g/cm3, 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.
