Solvent- and Heat-Induced Polymorphic Transformation with Single-Crystal Integrity in Cu(II) Paddle Wheel Metal Complexes

Key Points

• The aim is to explore the single-crystal-to-single-crystal transformation of a Cu(II) complex and identify new polymorphs.
• Investigated the transformation of the Cu(II) paddle wheel complex
• Utilized solvent and heat treatments to induce changes
• Characterized the resultant polymorphs through crystallography.
• Identified two novel polymorphs of the Cu(II) complex
• Demonstrated successful single-crystal-to-single-crystal transformation
• Results highlight the role of solvent and heat in polymorphic behavior.
