Tetrakis(μ-benzoato-κ2O:O′)bis[(piperidine-κN)rhodium]
Autor: Detlef Selent, Hans-Joachim Drexler
Publikováno v: IUCrData, Vol 2, Iss 2, p x170205 (2017)
The title compound, [Rh2(C7H5O2)4(C5H11N)2], an adduct of dimeric rhodium(II) benzoate with piperidine, was prepared. The complex lies across an inversion centre with the unique RhII ion in a slightly distorted octahedral coordination environment.

Publikováno v: Chemometrics and Intelligent Laboratory Systems. 163:55-63
Multivariate curve resolution (MCR) methods as MCR-ALS, ReactLab, the peak group analysis and SVD-based hard-modeling methods differ in their algorithms and the underlying optimization procedures. These differences include variants in the implementat

Publikováno v: Catalysts
Volume 9
Issue 12
The stability of homogeneous catalytic systems is an industrially crucial topic, which, however, receives comparatively little attention from academic research. Phosphites are among the most frequently used ligands in industrial, rhodium-catalyzed n-
