Aminocyclophosphazene Derivatives of Tungsten Carbonyl
Reactions of aminated cyclotriand cyclotetra-phosphazenes, viz., N3P3L6 and N4P4L8 (L = -NC4H80 , -NC5H io, -HNC6Hn and -HNC8H ,7) with W(CO)6 have been studied. [(N3P3L6)W(CO)3] derivatives are obtained with N3P3L6 while N4P4L8 yield tetracarbonyl substituted derivatives, [(N4P4L8)W(CO)4]. Mixed ligand tungsten tricarbonyls of the type [Ci2HgN2)(N3P3L6 or N4P4Lg)W(CO)3] have also been synthesi...
متن کاملSynthesis and characterization of luminescent osmium(II) carbonyl complexes based on chelating dibenzoylmethanate and halide ligands.
Octahedral Os(II) complexes 1-5 with formula [Os(CO)3X(dbm)] are prepared through utilization of both solid-state pyrolysis and ligand exchange reactions. These complexes exhibit prominent 3pi-pi* phosphorescence with unusually long lifetimes (29-64 micros) and high quantum yields (0.08-0.13).
متن کاملEvidence for a zwitterionic transition state in double bond rotations within tungsten-vinyl complexes.
The trianionic pincer supported tungsten-vinyl complex [CF3-ONO]W(O){(CH3)3CC[double bond, length as m-dash]C(CH3)2} (3syn) undergoes facile double bond rotation at ambient temperature. The degenerate methyl exchange rates were measured via selective inversion-recovery experiments. DFT computations in conjunction with experimentally determined rate constants support a double bond rotation that ...
متن کاملSynthesis and Characterization of Hydrido Carbonyl Molybdenum and Tungsten PNP Pincer Complexes
In the present study the Mo(0) and W(0) complexes [M(PNP)(CO)3] as well as seven-coordinate cationic hydridocarbonyl Mo(II) and W(II) complexes of the type [M(PNP)(CO)3H]+, featuring PNP pincer ligands based on 2,6-diaminopyridine, have been prepared and fully characterized. The synthesis of Mo(0) complexes [Mo(PNP)(CO)3] was accomplished by treatment of [Mo(CO)3(CH3CN)3] with the respective PN...
متن کاملAdditive and Non-additive Ligand Effects in Mixed Halide-Carbonyl-Nitrile Osmium Complexes
In the series [OsX6]3-, [OsX5(CO)]2-, t ran~[OsX~(CO)~] l (X = Br) and the series t ran~[OsX~(MeCN)~] l , trans-[0sX4(MeCN)(CO)]1-, t rans[O~X~(CO)~l I , osmium IV/III and III/II redox couples shift two to three times further for the first introduction of CO than for the second, contrary to recent predictions; the corresponding halide to Oslll charge-transfer spectra (X = CI and Br) confirm the...
