Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 104-67-6, Name is Undecanoic gamma-Lactone, SMILES is O=C1OC(CCCCCCC)CC1, belongs to tetrahydrofurans compound. In a document, author is Chen Yu, introduce the new discover, SDS of cas: 104-67-6.
Crystal Structure and Properties of Metal-Organic Macrocycles and Metal-Organic Gels Based on Rigid Bis-imidazole Ligand
Complexes [Ag(4-PIM)]ClO4 (1) and [Zn(IPI)]Cl-2 center dot H2O (2) were synthesized by the reaction of ligand 2-(4-pyridinyl)-imidazole (4-PIM) and 2-(4-(1-imidazolylphenyl))-imidazole (IPI) with AgClO4 and ZnCl2, respectively. X-ray crystallography analysis reveals that complexes 1 and 2 have metal-organic macrocyclic structure of M4L4 and M2L2 type, respectively. And there are stronger intermolecular forces, pi-pi stacking effect and hydrogen-bonding interactions in the crystal structures of complexes. Metal-organic gels were formed by using rigid ligand IPI to react with AgNO3 and Zn(NO3)(2) in methanol, ethanol, dimethyl sulfoxide, ethylene glycol, tetrahydrofuran and acetonitrile, respectively. Supramolecular metal-organic gels were also self-assemblied through ligand IPI reacting with AgNO3, AgClO4, AgBF4, AgPF6, AgOSO2CF3, Zn(NO3)(2), Zn(BF4)(2), Zn(ClO4)(2) and Co(NO3)(2) in ethanol solvent, respectively. The hydrogen-bonding interactions between solvent molecules and N-H in the imidazole rings of ligand IPI may be the key factor to form gels. Scanning electron microscopy (SEM) images showed that metal-organic supramolecular gels based on silver salts or zinic salts had fluffy cotton-like and loose bread-like structure, respectively.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 104-67-6 is helpful to your research. SDS of cas: 104-67-6.
