Stereochemistry and EPR investigation of a chiral molecular magnet

Abstract

An electron paramagnetic resonance investigation of an indexed single crystal of the chiral molecular magnet ( R)- 3MLNN·Mn(hfac) 2 which is comprised of a chiral phenyl α-nitronyl nitroxide and a manganese(II) ion is presented. The crystal of the compound, which consists of ferrimagnetic chains of radical and metal ion and orders ferromagnetically below 4 K, shows temperature and angle-dependent spectra which may give clues as to the nature of the anisotropy in the system and the types of interaction at play.
