In 2016,Schmidt, Sven Olaf; Naggert, Holger; Buchholz, Axel; Brandenburg, Hannah; Bannwarth, Alexander; Plass, Winfried; Tuczek, Felix published 《Thermal and Light-Induced Spin Transitions of FeII Complexes with 4- and 5-(Phenylazo)-2,2′-bipyridine Ligands: Intra- vs. Intermolecular Effects》.European Journal of Inorganic Chemistry published the findings.Product Details of 13534-97-9 The information in the text is summarized as follows:
Five new spin crossover complexes with 4- and 5-(phenylazo)-2,2-bipyridine (4-/5-PAbipy) ligands were synthesized and investigated with respect to their spin crossover (SCO) behavior. The results are compared to the thermal and light-induced spin transition properties of the parent SCO complexes [Fe(bpz)2(bipy)] (1) and [Fe(bipy)2(NCS)2] (2) (bpz = dihydro(bispyrazolyl)borate). [Fe(bpz)2(4-PAbipy)] (1a) undergoes a stepwise spin transition whereas [Fe(bpz)2(5-PAbipy)] (1b) exhibits a 1-step transition with a 6 K-wide hysteresis. For [Fe(bpz)2(tBu5-PAbipy)] (1c) the spin transition to the low-spin state is incomplete. Qual. similar changes of the SCO behavior are observed for [Fe(4-PAbipy)2(NCS)2] (2a) and [Fe(5-PAbipy)2(NCS)2] (2b). In comparison to the parent system 2, a strengthening of intermol. interactions leads to a stabilization of the low-spin state. Evidence for the LIESST behavior could be obtained for all new compounds by magnetic susceptibility measurements as well as UV/visible and resonance Raman spectroscopy. The results came from multiple reactions, including the reaction of 6-Bromopyridin-3-amine(cas: 13534-97-9Product Details of 13534-97-9)
6-Bromopyridin-3-amine(cas: 13534-97-9) belongs to anime. Large quantities of aliphatic amines are made synthetically. The most widely used industrial method is the reaction of alcohols with ammonia at a high temperature, catalyzed by metals or metal oxide catalysts (e.g., nickel or copper). Mixtures of primary, secondary, and tertiary amines are thereby produced.Product Details of 13534-97-9
