Structural Motifs in Aryl Organogermanium Ge-O Derivatives for Material Design

The aim of this work was to understand the main structural features and ways of formation of Ge-O bonds in organogermanium compounds under the conditions of Ar(n)GeHal(4-n) (Hal = halide) hydrolysis. The structural types of these compounds were considered, providing 11 blocks (A-K). The molecular structures of the novel compounds [(p-FC6H4)(3)Ge](2)O (1), [(p-F3CC6H4)(3)Ge](2)O (2), and cyclo-[(p-F3CC6H4)(2)GeO](4) (3) were studied through XRD (X-ray diffraction) analysis. The molecular structure of [(p-F3CC6H4)(3)GeO](4)Ge (4), representing a novel structural type, was also investigated. The data presented in this study will be important in the design of materials with useful properties based on group 14 element derivatives with element-oxygen bonding.
