Molybdenum(VI) Bisimidoaryl Phenoxide and Alkoxide Complexes: Molecular Structures of [Mo(NAr)2(OCMe2-2-py)(CH2SiMe3)] and [{Mo(NAr)2Me(OMe)}2]

Synthesis, spectroscopic characterization and X-ray crystal structures of oxo-bridged oxo(haloaryl) imido hydrotris(3,5-dimethylpyrazolyl)borate molybdenum(V) complexes

“…There are several molybdenum imido compounds [10][11][12][13][14][15] and a number of related mixed terminal oxo-imido compounds reported [16][17][18][19][20][21] but limited information is available for transition metal compounds containing both imido and hydrotris (pyrazolyl)borate type ligands [16,[22][23][24][25][26][27][28][29]. Although a number of systems involving m-ligation in the presence of terminal imido groups have previously been reported [30][31][32][33][34][35][36][37], the chemistry of compounds having both arylimido and m-oxo groups in the presence of tris(pyrazolyl)borate co-ligand is not widely explored.…”

Metal Complexes of Macrocyclic Schiff‐Base Ligand: Preparation, Characterisation, and Biological Activity

“…In addition, the IR spectra of the complexes display peaks around 1620 cm −1 , which may be attributed to the ν (C=N) imine stretching of the uncoordinated moieties. Further, bands in the region of 1518–1550 cm −1 in all the complexes suggest phenoxide bridging with the metal atoms [22, 23]. At lower frequency, the complexes exhibited bands around 619–688 and 516–584 cm −1 , which could be assigned to ν (M–N) and ν (M–O) vibration modes, respectively [19, 24].…”

“…21 The three absorption peaks at 1540 cm suggest that phenoxide bridging with the metal atom are existed, 22,23 and peak 1090 cm ¹1 indicates the presence of C-O stretch vibrations. Similar to C=N imine stretching band, C-O is also split by Fermi resonance, which is assigned by peak 1120 cm ¹1 .…”
