Structure and bonding lie at the heart of modern inorganic chemistry. It is not too much to say that the renaissance of inorganic chemistry following World War II was concurrent with the development of a myriad of spectroscopic methods of structure determination. Methods of rationalizing and predicting structures soon followed. Following these guideline, our work concerns the synthesis of small inorganic covalent molecules, many of them being novel species for which no preparation methods are reported in the literature. The main objective is the study of the structural, conformational and electronic properties, focusing the analysis on the synthesized molecules, which are tailored in such a way that systematization on the results is attainable, for instance through the preparation of similar related species inside a given class of compounds. The chemical families under study can be classified as belonging to the non-metallic main group of the Element Chart, emphasizing in the Chalcogen main group (Group XVI). Among others, we have studied representative molecules from the following families: sulfenylcarbonyl –SC(O)–, oxoesters –OC(O)–, sulfonates –SO2O–, disulfides –SS– and peroxides –OO–.
