Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. In an article, author is Muhammad, Waseem, once mentioned the application of 37622-90-5, Name is Ethyl 4-pyrazolecarboxylate, molecular formula is C6H8N2O2, molecular weight is 140.14, MDL number is MFCD00010844, category is pyrazoles-derivatives. Now introduce a scientific discovery about this category, Formula: C6H8N2O2.
Synthesis, structure and magnetic properties of a decanuclear Fe(III)/oxo cluster
An iron (III) cluster, namely [Fe-10(mu(3)-O)(8)L-8(NO3)(6)] (1), has been synthesized by treatment of Fe(NO3)(3)center dot 9H(2)O with 3,5-dimethyl-1-(hydroxymethyl)-pyrazole (HL) under ambient temperature. The core skeleton of {Fe-10(III)} can be regarded as a pear-like cage with eight triangular {Fe-3(III)(mu(3)-O)} units, in which each three Fe-III centers is held together by one mu(3)-O2- group with Fe-III centers as corner-sharing triangle units. Importantly, {Fe-10(III)} cluster is not only stable in solid state but also in solution, which is confirmed by powder X-ray diffraction (PXRD) pattern and electrospray ionization mass spectrometry (ESI-MS), respectively. Furthermore, 1 shows antiferromagnetic exchange behavior arising from the interactions between the iron(III) centers.
