摘要

New semi-organic bis(hydrogenmaleate)-Cu(II) tetrahydrate single crystal was grown by the slow evaporation method, and its structure belong to the triclinic system with centrosymmetric space group P-1. The structure of crystal was determined using X-ray diffraction analysis. BMCT has the highest O⋯H interaction (55.4%), which stabilize the crystal structure. The linear optical characteristics, including bandgap energy, refractive index, and extinction coefficient, were utilized to assess the optical activity of BMCT. The emission behaviour of grown crystal has been examined using fluorescence spectral analysis. Thermal analysis clarified BMCT’s thermal stability. The intramolecular charge transfer (ICT) and hyperconjucative contacts were interpreted using NBO analysis. Using Z-scan analysis, the self-defocusing effect was investigated in BMCT.
