This dissertation details the synthesis and characterization of novel homo- and heterometallic single-source molecular precursors of vanadium and chromium, exploring their conversion into binary and ternary oxides. The study is organized into four main parts focusing on vanadium and chromium molecules and their applications in materials synthesis. The first part showcases the development of new air-stable homoleptic and heteroleptic vanadium (III) and (IV) heteroarylalkenolates, which serve as precursors for selectively obtaining oxide materials. The second part elaborates on the synthesis and characterization of heterobimetallic and trimetallic alkoxide precursors with a defined metal–metal ratio, facilitating the creation of ternary and quaternary oxide nanomaterials. This section highlights the potential for trimetallic alkoxide formation by combining lithium with vanadium in various ratios. Part three introduces a synthetic approach that allows for phase-selective synthesis of metastable chromium oxide nanomaterials, utilizing bifunctional O, N chelating ligands as key components in homoleptic chromium (II) and (III) complexes. The final part illustrates the fabrication of phase-selective LiCrO2 and Li2CrO4 nanoparticles from newly synthesized heterometallic chromium(III)-based alkoxides, achieved through an efficient solvothermal method, with stabilization via ligand modification using specific compounds.
