| Abstract: | Cyclic trimeric perfluoro-o-phenylenemercury (o-C6F4Hg)3 readily reacts with N,N-dimethylacetamide and n-butyronitrile to form the complexes {(o-C6F4Hg)3](MeCONMe2)2} and {(o-C6F4Hg)3](PrnCN)}, respectively. According to X-ray diffraction data, the amide ligands are located above and below the plane of the macrocycle, each being coordinated to all Hg atoms of the macrocycle through the O atom. The nitrile ligand is bound to the macrocycle through the N atom, all Hg atoms being also involved in this bonding. |
