Synthesis and characterization of new dioxomolybdenum(VI) complexes derived from benzophenone-thiosemicarbazone (H₂L). Crystal structure of [MoO₂L(PrOH)]

SYNTHESIS AND STUDIES OF SOME cis- MoO2(VI) COMPLEXES WITH NITROGEN DONOR MACROCYCLIC LIGANDS

“…The dioxomolybdenum(VI) complexes revealed two Mo=O stretching bands at 893-910 cm -1 and 964-981 cm -1 due to asymmetric and symmetric stretching vibrations of the cis-[MoO2] 2+ moiety with C2V symmetry. 60 Those two IR spectral bands are allocated to νasym(O=Mo=O) and νsym(O=Mo=O) vibrations, respectively. 60-66 νasym(O=Mo=O) vibrations are lower than ones of νsym(O=Mo=O).…”

Synthesis and characterization of cis-dioxomolybdenum(VI) complexes having furil as precursor molecule

“…18 The dioxomolybdenum(VI) complexes prefer to form a cis-dioxo group due to the maximum utilization of the d-orbital for bonding. The cis-dioxo configuration in the dioxomolybdenum(VI) moiety [20][21][22] is characterized by two infra-red bands, ν asym (O=Mo=O) and ν sym (O=Mo=O) in C 2V symmetry. The presence of two infra-red bands in the 898-910 cm -1 and 935-945 cm -1 regions are assigned to ν asym (O=Mo=O) and ν sym (O=Mo=O) vibrations, respectively.…”

Syntheses and Spectroscopic Studies on Macrocyclic Complexes of Dioxomolybdenum(VI) with Furil as Precursor

“…18 The dioxomolybdenum(VI) complexes prefer to form a cis-dioxo group due to the maximum utilization of the d-orbital for bonding.. The cis-dioxo configuration in MoO 2 (VI) moiety [19][20][21] is characterized by two infra-red bands of ν asym (O=Mo=O) and ν sym (O=Mo=O) in C 2V symmetry. The presence of two infra-red bands in the 900-912 cm -1 and 930-940 cm -1 regions are assigned to ν asym (O=Mo=O) and ν sym (O=Mo=O) vibrations respectively.…”
