Synthesis, spectroscopic characterization, X-ray structure and DFT calculations of p-tolylimido rhenium(V) complexes of 2,2′-dipyridylamine
摘要:
The imido rhenium(V) complexes [Re(p-NC6H4CH3)X(OMe)(Hdpa)(PPh3)]ReO4 (Hdpa = 2,2'-dipyridylamine and X = Cl in 1 and Br in 2) have been synthesized and characterised spectroscopically and structurally (by single-crystal X-ray diffraction). The experimental studies on 1 have been accompanied computationally by the density functional theory (DFT) and time-dependent OFT calculations. Additional information about the Re-NR bond characteristics in [Re(p-NC6H4CH3)Cl(OMe)(Hdpa)(PPh3)(+) was obtained by NBO analysis. (C) 2013 Elsevier Ltd. All rights reserved.
