In this study, geometrical optimization, IR vibration frequencies, and HOMO-LUMO energy differences at various temperatures of the compound were calculated by DFT. It is realised that the computed splitting energies and splitting free enthalpies together with the mole fraction of HS state are compatible with the experiment.en10.1007/s10948-017-4004-xinfo:eu-repo/semantics/closedAccessSpin CrossoverDFTIR SpectraHOMO-LUMOCrossoverComplexArticle301130653070Q4WOS:0004120854000102-s2.0-85013218982Q3
