| 英文摘要 | Covalency and ionicity are key concepts in chemical science. Here we report a systematic investigation of the electronic structures and chemical bonding of [MX2](-) (M = Cu, Ag, Au, Rg; X = H, Cl, CN) to illustrate the periodicity and covalency of the group 11 binary compounds. Various modern chemical bonding theories have been utilized to analyze the interactions between the metal ions and ligands. The energy decomposition approach (EDA) results suggest that the strength of the metal-ligand bonding in [MX2](-) increases from Cu to Rg. Both relativistic effects and electron correlation play vital roles in the periodicity and enhancement of covalency in the heavier binary complexes. A gradual transition from Cu-X bonding with apparent ionic character to Rg-X bonding with relatively strong covalent character has been revealed from the chemical bonding analyses. The covalency of the M-X bond is enhanced by the strong relativistic effects of the metal and the decreased electronegativity of the ligands. In all the complexes studied, the monovalent metal(I) atoms interact with the neighboring atoms through significant s-d hybridizations. Spin-orbit coupling is found to be significant in [RgX(2)](-), and the splitting energy of the spinors is as large as 2.5 eV. |
