Supramolecular frameworks of binuclear dioxomolybdenum(vi) complexes with ONS donor ligands using 4,4′-azopyridine as a pillar: crystal structure, DFT calculations and biological study

“…Other LMCT bands which may be assigned to nitrogen to molybdenum and oxygen to molybdenum charge transfer transitions are observed in the 299-294 nm range. [66][67][68][69]…”

Lewis base controlled supramolecular architectures via non-covalent interactions of dioxomolybdenum(vi) complexes with an ONS donor ligand: DFT calculations and biological study

“…Other LMCT bands which may be assigned to nitrogen to molybdenum and oxygen to molybdenum charge transfer transitions are observed in the 311-297 nm range. [50][51][52][53] Electrochemistry Cyclic voltamograms of the ligand (H 2 L) and [MoO 2 LB] complexes 1-5 at a Pt electrode were recorded in dry degassed DMF containing 0.1 (M) TBAP as the supporting electrolyte over the potential range 0.00 to À1.10 V. The numerical data are given in Table 1. Each complex (1-5) shows only one irreversible two-electron one step reduction within the potential range À0.68 to À1.20 V vs. SCE which corresponds to a Mo(VI)/Mo(IV) process.…”

“…The C(9)-N(2) bond distances in 1-4 are similar and close to the usual CQN length. 16,52 In complex 1, an infinite 1D chain is formed through C( 13)-H(13)Á Á ÁO(3) hydrogen bonding interactions (black dotted line) (Table 3). The oxo oxygen cis to the Lewis base (THF) is involved in hydrogen bonding with the ring hydrogen atom of the S-benzyl moiety.…”

Chemical, electrochemical and structural studies of somecis-dioxomolybdenum(VI) complexes of two tridentate ONS chelating ligands

“…Other LMCT bands are observed in the region 350-294 nm [30,38,48,50]. These bands may be assigned as nitrogen to molybdenum and oxygen to molybdenum charge transfer transitions [17], respectively.…”
