Title Manganese(II)octabutoxynaphthalocyanine and its ferrimagnetic electron-transfer salt with TCNE
Date 2000
Description The magnetic susceptibility (x) of 1,6,10,15,19,25,28,32- octa-n-butoxynaphthalocyaninatomanganese(III) tetracyanoethanide can be fit to a Curie-Weiss expression with O=54 K for T>150 K, and the xT(T) data are consistent with linear chains and can be fit to a Seiden expression for alternating S=2 and S=1/2 antiferromagnetically coupled spin sites with a coupling constant, Jintra1kB (H=-2JSa.Sb) of -145 K. Hysteresis with a coercive field of 1.6 kOe was observed at 2 K. The magnetic ordering temperature, Tc, determined from both the maximum in the 10 Hz ac susceptibility, x'(T), and the irreversibility of low field zero field cooled/ field cooled magnetization data, was determined to be 9.0 K. This is the first example of a metallophthalocyanine electron transfer salt that magnetically orders.
