Autor: Irina A. Kühne, Kane Esien, Laurence C. Gavin, Helge Müller-Bunz, Solveig Felton, Grace G. Morgan
Publikováno v: Molecules, Vol 25, Iss 23, p 5603 (2020)
Spin state preferences for a cationic Mn3+ chelate complex in four different crystal lattices are investigated by crystallography and SQUID magnetometry. The [MnL1]+ complex cation was prepared by complexation of Mn3+ to the Schiff base chelate forme
