| Abstract: | The reactions of three-mercury anticrown (o-C6F4Hg)3 (1) with acetoacetic ester (AE), malonic ester (ME), and malonodinitrile (MN) afford 1: 1 complexes {(o-C6F4Hg)3](AE)} (3), {(o-C6F4Hg)3](ME)} (4), and {(o-C6F4Hg)3](MN)} (5). The structures of complexes 3–5 were determined by X-ray diffraction analysis. Complex 3 has a discrete structure in the solid state, whereas complexes 4 and 5 form in the crystal extended stacks representing polydecker sandwiches with alternating molecules of 1 and ME or MN. According to the X-ray diffraction and IR spectral data, the molecule of AE in complex 3 is in the keto form. |
