Zinc(II) and Cadmium(II) Coordination Compounds with Boron Cluster Anions: Classification of Compounds Depending on Strength of Metal-Boron Cage Interaction and Analysis of Structures (Review)

Data on the synthesis and structures of Zn(II) and Cd(II) complexes with boron cluster anions [BnHn](2-) (n = 6, 10, 12), their substituted derivatives, as well as analogs-carboranes and metallaboranes-in the presence of competitive organic ligands are generalized and summarized. The synthesis and structural features of the obtained compounds, isomeric composition of the compounds, and influence of the reaction conditions on the composition and structures of the final products are discussed. A classification of compounds is given depending on the strength of the metal-boron cage interaction.

Automated summary

This paper provides a summary and discussion on the synthesis and structural features of Zn(II) and Cd(II) complexes with boron cluster anions, as well as the influence of reaction conditions on the composition and structures of the final products. A classification of compounds based on the strength of the metal-boron cage interaction is also presented.
