Ionic liquid syntheses have proven proficiency in the production of metal oxides with diverse functionalities. In this work we use the potential of these solvents to form multicationic solutions to directly synthesize five strontium niobate metastable crystal compositions. Such metastable crystals are characterized via UV-vis spectroscopy, inductively coupled plasma optical emission spectrometer, powder X-Ray diffraction, high-resolution transmission electron microscopy, and crystalline refinements. All metastable crystalline structures are strontium rich with Sr/Nb molar ratios Sr/Nb = 3.54, 3.23, 3.09, 2.66, and 2.22, and are consistent with triclinic with space group P-1 (2).
