The title compound, [Rh(C(5)H(7)O(2))(C(18)H(12)Cl(3)P)(CO)], contains the bidentate acetyl-acetonate ligand coordinated to the Rh(I) atom, forming a chelate ring [Rh-O = 2.0327 (15) and 2.0613 (14) Å]. The Rh(I) atom is additionally coordinated by one P [Rh-P = 2.2281 (6) Å] and one carbonyl C [Rh-C = 1.812 (2) Å] atom, resulting in a slightly distorted square-planar geometry. The mol-ecules a...

Estimation of the warfarin dose with clinical and pharmacogenetic data. N Engl J Med. 2009; 360(8): 753-764. 27. Teichert M, Eijgelsheim M, Rivadeneira F, Uitterlinden AG, van Schaik RH, Hofman A, et al. A genome-wide association study...
Naturally occurring phytoferritin is a heteropolymer consisting of two different H-type subunits, H-1 and H-2. Prior to this study, however, the function of the two subunits in oxidative deposition of iron in ferritin was unknown. The data show that, upon aerobic addition of 48-200 Fe(2+)/shell to apoferritin, iron oxidation occurs only at the diiron ferroxidase center of recombinant H1 (rH-1)....
let h be a separable hilbert space and let b be the set of bessel sequences in h. by using several interesting results in operator theory we study some topological properties of frames and riesz bases by constructing a banach space structure on b. the convergence of a sequence of elements in b is de_ned and we determine whether important properties of the sequence is preserved under the con...
A single-Rh-site catalyst (Rh-TPISP) that was ionically-embedded on a P(V) quaternary phosphonium porous polymer evaluated for heterogeneous ethanol carbonylation. The [Rh(CO)I3]2– unit proposed to be the active center of Rh-TPISP carbonylation reaction based detailed Rh L3-edge X-ray absorption near edge structure (XANES), photoelectron spectroscopy (XPS), and extended fine (EXAFS) analyses. A...
We report the addition of M-H bonds (M = Al, Zn, Mg) to a Rh(iii) intermediate generated from the reductive elimination of triethylsilane from [Cp*Rh(H)2(SiEt3)2]. A series of new heterobimetallic complexes possessing Rh-M bonds have been isolated and characterised by a number of spectroscopic (1H, 29Si, 13C, 103Rh NMR, infrared, and X-ray diffraction) and computational techniques (NBO and QTAI...
The interaction of binuclear rhodium(II) complexes [Rh(2)(OOCCH(3))(4)(H(2)O)(2)], [Rh(2){OOCCH(OH)Ph}(2)(phen)(2)(H(2)O)(2)] {OOCCH(OH)Ph}(2), [Rh(2)(OOCCH(3))(2)(bpy)(2)(H(2)O)(2)](OOCCH(3))(2) and [Rh(2)Cl(2)(OOCMe)(2)(bpy)(2)](3H(2)O) with ceruloplasmin, cysteine, glutathione and coenzyme A have been investigated using. UV-Vis and CD spectroscopies. The complexes containing phen or bpy at p...
The title compound, trans-[RhCl(C(18)H(14)BrP)(2)(CO)], has a slightly disordered square-planar geometry with the Rh ion(I) situated on an inversion the centre and carbon-yl-chloride disorder observed as a result of the crystallographic inversion symmetry. Selected geometric parameters include: Rh-P = 2.3430 (8) Å, Rh-Cl = 2.434 (3) Å, Rh-C = 1.722 (8) Å, P-Rh-P = 180.00 (3)°, P-Rh-Cl = 95.40 (...
The μ-amino-borane complexes [Rh2 (L(R) )2 (μ-H)(μ-H2 B=NHR')][BAr(F) 4 ] (L(R) =R2 P(CH2 )3 PR2 ; R=Ph, (i) Pr; R'=H, Me) form by addition of H3 B⋅NMeR'H2 to [Rh(L(R) )(η(6) -C6 H5 F)][BAr(F) 4 ]. DFT calculations demonstrate that the amino-borane interacts with the Rh centers through strong Rh-H and Rh-B interactions. Mechanistic investigations show that these dimers can form by a boronium-me...
The title compound, trans-[RhCl(C(18)H(12)Cl(3)P)(2)(CO)]·C(3)H(6)O, contains an Rh(I) atom in a distorted square-planar coordination with a P-Rh-P angle of 175.27 (2)° and Rh-P bond lengths of 2.3127 (4) and 2.3219 (4) Å. The rhodium complexes link each other through weak inter-molecular contacts between the acetone methyl groups and the carbonyl O atom. Inter-actions between the acetone solve...
