Abstract:

The magnetic properties of the complex MnLL′ (L: mnt2-,  maleonitriledithiolate:  L′=phen-5, 6-dione, 1, 10-phenanthroline-5, 6-dio ne) were characterized by variable-temperature susceptibility and EPR of solid powder, EPR in DMSO, DMF and acetone solutions. The title complex MnLL′is hi gh spin tetracoordinate complex. The complex MnLL′possess remarkable paramagnet ism. Experiment fact of EPR of MnLL′is explained by theory.

Key words: dithiolate, phenanthroline-5, 6-dione, manganese, sy nthesis, magnetism
