A general method for synthesis of supported metal complexes having a high degree of uniformity is presented, whereby organometallic precursors incorporating acetylacetonate (C(5)H(7)O(2)(-), acac) ligands react with zeolites incorporating OH groups near Al sites. The method is illustrated by the reactions of Rh(acac)(CO)(2) and of cis-Ru(acac)(2)(eta(2)-C(2)H(4))(2) with zeolites slurried in n-...

A DFT/TDDFT investigation was conducted on a series of cyclometalated iridium(iii) complexes with 2,5-diaryl-1,3,4-oxadiazole (oxd(n)) derivatives to shed light on the effects of the stereoisomeric and steric factors on the photophysical properties. On the basis of the results reported herein, we attempt to explain the experimental observations according to which complexes N,N-trans [Ir(oxd(0))...

neutral bidentate n-o type complexe of vo(ii) has been synthesized through condensation of dpenicillamine,(d-h2pen), with bis(acetylacetonate)- oxovanadium(iv),[vo(acac)2], at neutralmedium . the established schiff base(no type) complex was characterized on the basis of ir andmass spectroscopy techniques.besides,d-h2pen binding behavior to[vo(acac)2] has been studiedin thermodynamic viewpoint u...

Abstract The structurally related cobalt β‐diketonate complexes Co(acac) 2 , ⋅ TMEDA, Co(tfac) and Co(hfac) TMEDA (acac=2,4‐pentanedionate, tfac=1,1,1‐trifluoro‐2,4‐pentane‐dionate, hfac=1,1,1,5,5,5‐hexafluoro‐2,4‐pentane‐dionate, TMEDA= N ′, ′‐tetramethylethylenediamine) were thermochemically (thermogravimetric analysis, differential scanning calorimetry) spectroscopically (infrared, UV‐VIS el...
