Normal coordinate analysis and quantum chemical study of tris(p-fluorophenyl)antimony di(N-phenylglycinate) [(p-FC6H4)3Sb(O2CCH2NHC6H5)2]

Abstract

A complete normal coordinate analysis was performed by two different methods: a classical Wilson's G-F matrix method and the semi-empirical molecular orbital PM3 method, for a five coordinate tris(p-fluorophenyl)antimony di(N -phenylglycinate) [(p-FC6H4)3Sb(O2CCH2NHC6H5)2], known to be an in vitro antitumour molecule.

Three-Dimensional Polypyrrole Nano-Network with Sb Nanocrystals as Electrode Material for Sodium-Ion and Lithium-Ion Batteries

“…All the absorption bands reveal the presence of ppy in the Sb@ppy NNW. 39,40 The peak around 449 cm −1 likely represents the interaction between Sb and the ppy C (Sb-C vibration), 41 and the peak at 2375 cm −1 is associated with the presence of CO 2 . Figure S1 (Supporting Information is available online at stacks.iop.org/JES/167/020527/ mmedia) shows the FTIR spectrum of the ppy-NNW, which exhibits similar peaks to the Sb@ppy NNW.…”

Vibrational and Quantum Chemical Study of Triphenylantimony (V) Benzilate SbPh3 [O2CC (OH) Ph2]2

“…We have used Urey Bradley force field [9] in our calculations, which takes into account both bonded, and nonbonded interactions and internal tensions. For the assignments, the force constants were initially transferred from our earlier work and literature [13][14][15][16][17][18][19][20] and were further refined by least square fit method to provide best match with the observed FT-IR spectra. In the assignment of the normal modes, as given in Table I, only the dominant potential energies distributions (PED's) are considered.…”

“…The physical effects represented by these parameters are Vander Waals and electrostatic forces. Identification with the experimental data has been made on the basis of potential energy distribution, line profile, line intensities and the presence/absence of a given mode in similar molecules [20][21][22][23] .
