摘要：
1-Ethyl-2-(phenylazo)imidazole (PaiEt, 2) and 2-(arylazo)pyrimidines (Raapm) (R=H (3a), p-Me (3b), p-Cl (3c)) are used to synthesize mercury(II) compounds. The complexes are characterized by elemental analysis, IR, UV-Vis, H-1 NMR spectral data and single crystal X-ray structures of di[chloro-{1-ethyl-2-(phenylazo)imidazole}(mu-chloro)-mercury(II)] (4) and di[chloro-{2-(phenylazo)pyrimidine) (mu-chloro)-mercury(II)] (5a). The first complex is a centro-symmetric dimer with two highly asymmetric chlorobridges which make the rhombohedral plane. The second complex forms an unsymmetric trapezohedral geometrical structure.
