Abstract
Three new Cd(II) complexes incorporating both 2-(1H-imidazol-1-methyl)-1H-benzimidazole (imb) and 1,4-benzenedicarboxylate (bdic2−), [CdCl(bdic)1/2(imb)2]n (1), {[Cd(bdic)(imb)(H2O)]·DMF·2H2O}n (2), and [Cd(bdic)(imb)]·3H2O}n (3), have been prepared and structurally characterized by single crystal X-ray diffraction. Bdic2− anions connect the⋯Cd-imb-Cd-imb⋯chains leading to a 2-D structure of 1. Bdic2−(A) and bdic2−(B) anions link the binuclear [Cd2(imb)2(H2O)2] units forming a 2-D structure of 2. Complex 3 features a 2-D structure involving supramolecular “double-layer” motifs. IR spectra and thermogravimetric curves are consistent with the results of the X-ray crystal structure analysis; 1–3 exhibit good fluorescence in the solid state at room temperature.
