In an effort to understand the structure-property relationship in magnetically frustrated systems, ruthenium-based (S= 3/2) oxides Li3Mg2RuO6 and Ca2ScRuO6 were investigated. The orthorhombic analog of Li3Mg2RuO6 has been successfully synthesized in an ordered rock salt structure type. This study focuses on the synthesis, characterization and physical property measurements of the monoclinic Li3Mg2RuO6 and compares the resultant magnetism with the orthorhombic structure. This work also focuses on the synthesis, characterization and physical property measurements of the novel B-site ordered double perovskite Ca2ScRuO6. This 4d3 system is compared to the isoelectronic and isostructural Os-based compound
