Recently, machine learning (ML) methods have gained popularity and have performed as powerfully predictive tools in various areas of academic and industrious activities. In comparison, their application in catalysis has been underdeveloped. Relying on the rapid development of different algorithms and their implementation, it is the right timing to harvest the potential of ML.
Pyridine is a Lewis base, donating its pair of electrons to a Lewis acid. One example is the sulfur trioxide pyridine complex (melting point °C), which is a sulfation agent used to convert alcohols to sulfate esters. Pyridine-borane (C 5 H 5 NBH 3, melting point 10–11 °C) is a mild reducing ance: Colorless liquid.

On checking the values of descriptor No. 1 for each complex in Table S5, we find that the number of aromatic bonds is 20 for complexes 1–5 but 19 for other Fe complexes.
This indicates that in addition to the ring-strain, the degree of conjugation in the complex Cited by: 1. The ligand, Cu(II), and Ni(II) complexes were doped with iodine by mixing 1 g ( mole) ligand, 1 g ( mole) Cu-complex, and 1 g ( mole) Ni-complex with 25 mL of iodine solution in CCL 4 (4%, w/v), the mixture was refluxed with stirring for 48 hours and then filtered and dried in the vacuum oven at 50° by: 3.
Complex Formation of Magnesium(II) with Octaaryltetraazaporphyrins in Pyridine Article in Russian Journal of General Chemistry 71(7). Infrared Spectral Data. The infrared spectrum of [Ni(C 5 H 5 N) 2 Cl 2] complex is shown in Figures 1 and 2 and the absorption bands are listed with the relative intensities along with tentative assignments of the various bands in Table the spectrum of the complex, absorption bands at – cm −1 and – cm −1 are due to the stretching vibration of C–H Cited by: 8.
The first book to didactically illustrate this particular, prominent class of supramolecular building-blocks covers topics ranging from terpyridine syntheses, via their chemistry and properties, supramolecular structures, and multinuclear metal complexes, right up to functionalized polymers, 3D-architectures, and able for students and lecturers in chemistry.
The successful formation of the metal-ligand complex was proven by Fourier transform infrared (FT-IR) spectroscopy and by 1 H NMR spectroscopy. Furthermore, the shape-recovery behavior was studied in detailed fashion and even triple-shape memory behavior could be : Josefine Meurer, Julian Hniopek, Stefan Zechel, Marcel Enke, Jürgen Vitz, Michael Schmitt, Jürgen Po.
The 1 H NMR spectra of the complexes 4–6 were recorded at room temperature using DMSO-d 6 as a solvent. The spectra of the complexes showed nearly the same signals appeared in the spectra of ligands with slightly downfield shift, which may be due to complex formation of the C=O and the pyridinyl nitrogen with metal by: 9.
The ability for shape-recovery is not particularly based on one specific property of the polymer. It results from the structure as well as the morphology of the whole polymeric system .Thus, shape-memory polymers need at least two different structural units: a stable network, which is responsible for the stability of the whole polymer and determines the permanent shape and a Author: Josefine Meurer, Julian Hniopek, Stefan Zechel, Marcel Enke, Jürgen Vitz, Michael Schmitt, Jürgen Po.

"Ammine" is spelled this way due to historical reasons; in contrast, alkyl or aryl bearing ligands are spelt with a single "m". Almost all metal ions bind ammonia as a ligand, but the most prevalent examples of ammine complexes are for Cr(III), Co(III), Ni(II).
