A complex [Cd₂(tbb)Cl₄]·4DMF·3H₂O, where tbb is 1,2,3,4-tetra(1H-benzo[d]imidazol-2-yl)butane, was synthesized and characterized by X-ray single-crystal structure analyses. For this complex: C₄₄H₄₉Cd₂C₁₄N₁₂O₇, M_r=1224.55, monoclinic system, space group C2/c, a=29.563(3), b=14.2580(17), c=26.355(3)Å, β=97.036(2)°, V=11025(2)Å³, Z=8, D_c=1.475 g/cm³, λ=0.71073Å, μ(MoKα)=1.021 mm^-1, F(000)=4936, S=1.047, R=0.0680 and wR=0.1832 for 11812 observed reflections with I>2σ(I). It is a neutral dinuclear complex. One 1,2,3,4-tetra(1H-benzo[d]imidazol-2-yl)butane coordinates to two cadmium ions. Each cadmium ion is coordinated by two nitrogen atoms of tbb and two chloride ions. The complex emits blue luminescence in DMF solution as well as in solid powder state.
