Abstract

Ethyl-5-methyl-4-imidazolecarboxylate (emizco) is an important intermediate in the synthesis of pharmacological active compounds. In this work, there were synthetized and characterized the following coordination compounds with emizco: trans-[Co(emizco)2(H2O)2](NO3)2 1, trans-[Ni(emizco)2(H2O)2](NO3)2 2, trans-[Cd(emizco)2(H2O)2](NO3)2 (3) and cis-[Cd(emizco)2Br2] (4). 2D or 3D supramolecular arrangements were stabilized. All nitrate trans octahedral compounds stabilized a 3D supramolecular arrangement via hydrogen bonding, throughout the nitrate anions, the ligand and the coordinated water molecules; the cis-octahedral halide complex formed a 2D pleated sheet arrangement, by intermolecular π stacking and halide-hydrogen bonding.
