“…While the dihedral angles at H33-C30-O29-C28, N27-C24-C25O29, C2-C25-C23-N27, N26-C24-C28-O29, C36-C37-C38-O50, H47-C45-O49-C39, C41-C40-C39-O49 and H48-C46-O50-C38 are identified at 167.79°, 0.79°, -129.85°, 178.79°, 176.15°, 170.90°, 176.21° and 170.82° respectively. When we compared our theoretical (DFT) values with experimental values of bond lengths O1-C23, N1-C7 and N2-C22 are 1.35Å, 1.32Å and 1.44Å, the bond angles are C23-O1-C26, C7-N1-C8 and C7-N2-C22 are 105.90°, 105.84° and 126.23° and the dihedral angles of N2-C15-C16C17 and O1-C23-C24-C25 are 96.00° and -2.05° respectively were found to be alike [23] . From this observed bond length, bond angle and dihedral angle, the compound (FMDI) have planar geometry.…”
