The title complex, [Co(2)(C(5)HF(6)O(2))(2)(C(5)H(7)O(2))(2)(H(2)O)(2)], is centrosymmetric with a crystallographic inversion center in the middle of the mol-ecule. The octa-hedrally coordinated Co(II) atoms are bridged by two chelating acetyl-acetonate (acac) ligands and two more electron-poor 1,1,1,5,5,5-hexa-fluoro-pentane-2,4-dionato (hfac) ligands are bonded terminally in a solely chelatin...

Herein we report the synthesis and photophysical study of tris-heteroleptic complexes of the general formula IrLL'(acac), where L and L' are two differently substituted 2-phenylpyridines (ppyH) and acacH is 2,4-pentanedione, using a combinatorial approach that could be employed for many ligand combinations. The tris-heteroleptic complexes and the analogous bis-heteroleptic complexes of the form...

( 1 ) O to the least-squares plane of the acac ring. Bond distance between the CY and P carbons of the naphthalene ring are shorter than the P-P bonds observed in other naphthalene derivatives. lo The naphthalene ring inclines slightly as the benzo group approaches N(2), and their dihedral angle is 87.6 (1)' to the least-squares plane of the acac ring. Since the inclination of the aromatic ring...

Figure S1. Density of states (DOS) for the periodic structures of TiO2 anatase (a), phenyl-acac-TiO2 (b), and 3-acac-pyran-2-one-TiO2 (c), calculated at the extended Hückel level. The filled black lines in (b)-(c) are the projected DOS of the dye chromophores. The blue arrows point to the electronic states with a predominant contribution of HOMO, and the red arrows point to the electronic state...

The co-extraction phenomenon was found in a typical chelate extraction system, in which the extraction of lanthanoid ion (Ln3+) with acetylacetone (Hacac) was highly enhanced by various metal ions (M(n+)) such as Cu2+, Al3+, and Zr4+. This phenomenon was ascribed to the formation of the 1:1 adduct between Ln(acac)3 and the M(acac),, extracted into the organic phase. The co-extraction occurred m...

In the present work, highly efficient oxidation of sulfides catalyzed by MoO2(acac)2 supported on multi-wall carbon nanotubes, MWCNTs, modified with 1,2-diaminobenzene (DAB) and 2-aminophenol (AP), at room temperature are reported. The effects of various parameters such as reaction time, solvent, catalyst amount, oxidant, etc, were studied. These heterogenized catalysts showed high activity in ...

The Alberta Cardiac Access Collaborative (ACAC) is a joint initiative of Alberta's health system to improve access to adult cardiac services across the patient journey. ACAC has created new care delivery models and implemented best practices across Alberta in four streams across the continuum: heart attack, patient navigation, heart failure and arrhythmia. Emergency medical providers, nurses, p...
