摘要：

A subtle interplay of covalent bond, hydrogen bond, aurophilic interactions, and steric hindrance controls the nuclearity and the luminescent properties of [Au{2-PyN= C(E)Me}](n) (E = O, NH) complexes. For E = O a molecular structure with n = 4 is formed, describing a 20-membered tetrametallacycle. For E = NH the structure formed shows a trigonal prismatic arrangement of six gold atoms formed by, gold-gold interactions between two gold triangles (n = 3 x 2). Both complexes display luminescent properties.
