Abstract
A new cadmium(II) complex with (1'H-[2,2']Biimidazoly-1-yl)-acetic acid (HBDAC) [Cd(BDAC)2(H2O)2]×H2O is synthesized and structurally characterized, which crystallizes in the monoclinic system, space group P21/c , a = 8.465(3) Å, b = 14.164(5) Å, c = 11.294(3) Å, α = 90°, β = 127.405(17)°, γ = 90°, Z = 2. The [Cd(BDAC)2(H2O)2]·H2O units are further bridged by O—H…O, N—H…O, C—H…O hydrogen bonds, π—π stacking and C—O…π interactions, generating a three-dimensional supramolecular structure. In addition, luminescence measurements reveal that complex 1 exhibits strong fluorescent emission in the solid state at room temperature.
